become a prey to the Geomalacus. Since then I have introduced more Vitrine, and a few of the following species:-Zonites glaber, Z. nitidulus, Z. purus, Z. crystallinus, two Helix fusca, two H. caperata, two H. hirsuta, and three Clausilia laminata, with the following results: all the shells representing the genus Helix are empty, with the shells more or less scraped away and perforated; all the Vitrina shells are empty, but left perfect; and some few of the Z. purus and Z. crystallinus are tenantless. The Clausilia and the other two species of Zonites remain untouched. Whether all these may have fallen victims to the rapacity of Geomalacus maculosus, may be questionable, but I would suggest that the probable cause of your last month's correspondent from Banbury finding so many of the Vitrina shells empty, might be owing to the ravages of the black slug, Arion ater, and its congener the Arion hortensis. Experiments carefully observed would no doubt determine this point. Allow me to say further, that in my experiment with the Geomalacus I added occasionally a piece of carrot, which seemed to suit the taste of this rare Irish slug; also a dead shell of Succinea putris has been nearly eaten away.-Thos. Rogers.

DOES THE MOON AFFECT LUNATICS ?-Could you inform me in what way the moon affects lunatics? Having heard that it did, and being unable to find it in any book, I should be glad if you could inform me through SCIENCE-GOSSIP.-R. P. U.

SPARUS.-On the 15th ult. a fisherman of Helford harbour brought to me a Sparus boöps, which he had just caught in a herring-net. It was twelve inches in length and two inches in depth. The silvery gleam of the body and of its yellow stripes was most brilliant; there were patches as of burnished gold in front of the eyes. The first British recorded specimen was caught near the entrance of Falmouth harbour in 1842, and was brought to my brother, Alfred Fox, who had a coloured drawing of it taken, of which Jonathan Couch published a copy in his valuable book on British fishes. It is a more faithful representation of this beautiful fish than that given by Bloch. Dr. Cocks, of Falmouth, sent a Boops, caught at a later period (in the same fishing-ground), to the British Museum. I have often seen this fish in the market of Algiers. The Sword-fish is justly esteemed there; its flesh is, I think, preferable to that of other Scomberidæ ; such as the Thunny or Mackerel. It probably swallows the blood and other juices of the fish that it wounds, as it is almost toothless. Its ear-bones must be very minute or rudimentary, as I could not discover any.-C. Fox.

THE SWORD-FISH.-The author of the article "Notes from the South Pacific," in the Leisure Hour for January, has not, in my opinion, "fallen into error in describing the Saw-fish as the Sword. fish;" at the same time, I have not seen a swordfish with the saw-like teeth which are figured in the cuts illustrating his paper. The Saw-fish (Pristis antiquorum), length in some instances, 12 to 15 feet (a specimen of which is in my possession), is of the Shark family, and has its head prolonged by a long flat plate, bearing osseous spines implanted like teeth on each margin, and resembling a saw. The specimen before me measures 34 inches in length, and has 26 teeth on each side, each tooth being 14 inch long. It was found in a river in Demerara. Your correspondent "E. H. R." is certainly right in saying it would be impossible for

the Saw-fish to penetrate the timbers of vessels with his saw," although it is a powerful weapon to attack whales and other cetaceous animals; whereas the Sword-fish is a well-known enemy to ships, one of these "swords" being found, some years ago, sticking to the depth of eighteen inches in the lower timbers of Her Majesty's ship Fawn. The writer in the Leisure Hour says the fish he describes has been pronounced "delicious" food by all who have tasted it; moreover the flesh of the Saw-fish is hard and ill-tasted. Upon the whole, it is clear that the fish described in the Leisure Hour, whatever species of sword-fish it may be, is not the Sawfish.H. Allingham.

FOSSILS. A correspondent in last month's SCIENCE-GOSSIP asks for information relative to corn-brash and forest marble fossils in the West of England. In answer thereto, I beg to state that in a little work published by Stanford, of Charing Cross, entitled "Geology of Weymouth and the Isle of Portland," there is a good deal of interesting matter relating to the above, with list of fossils &c.-T. W.

BRIMSTONE BUTTERFLY.-There is a variety of this species with orange-coloured patches in the fore wings, which occurs in France. Possibly it is a specimen of this variety to which Mr. H. Moore refers in his note in last month's SCIENCE-GOSSIP. A hybrid between two such widely separated species as Gonepteryx Rhamni and Colias Edusa would be most unlikely to occur.-Harry Leslie.

A WHITE BRIMSTONE (p. 95).-I scarcely believe Mr. Moore is justified in imagining that the butterfly referred to is a hybrid between G. Rhamni and Č. Edusa, since this, variety of the Brimstone and the typical form have both been reared from the same batch of eggs. This variety is occasionally met with. In the south of Europe a variety is met with called G. Cleopatra, in which the orange patches cover nearly the whole of the upper wings.-W. H. Warner, Kingston, Abingdon.

PASSION-FLOWER.-I have been told that the passion-flower was used in the early Christian churches as a symbolic reveration of faith, because of the resemblance discovered by some of the Catholic fathers in different portions of the flower to our Saviour's passion. Thus: the five anthers are the wounds; the stigmas represent the nails; the rays of the corona, the crown of thorns; and the ten parts of the perianth are apostles; Peter and Juda being absent-the one who betrayed, the other who denied our Lord.-H. E. Watney.

STARLINGS.-These birds, like swallows, are migratory birds. In the northern parts of this country, where the winters are severe, the Starling, on the approach of the cold season, wings its flight southward, returning to its old haunts about February or (if the season be inclement) March. In the south of England, during mild winters, they will often remain. At Charminster, a pretty little Dorset village, we had frequently the Starling all the year round, unless a very severe season set in, and then we missed them for a short time. The country people in Dorset are very fond of starling dumplings; and they are often sold for a shilling a dozen by the labourers. The chief winter food of starlings consists of berries of all descriptions; such as mountain ash, haws, and grain. A gentleman of my acquaintance used to make quite a friendship with a

colony of starlings which dwelt on the eaves of a neighbouring house. During the summer time, when the cherries were ripe, he used to lay some on his window-sill, and, being an invalid, it used to pass - many a weary hour pleasantly away, watching his pet starlings. During the two years of his confinement, those birds became quite tame and sociable, really looking out for their dessert and their handful of corn, which was daily placed for them. One day a friend sent him some starlings for a dumpling, when he remarked he would as soon think of turning cannibal as eating any of those poor starlings, for they had beguiled many a sad and painful hour, and their voices were heard first in the morning, and their cheerful chatter was his lullaby at eve. I do not fancy I could relish them myself, although I believe they are very savoury.-Barbara Wallace Fyfe.

THE STARLING.-In reply to "H. O. S.," the Starling is resident in England throughout the year, and is probably also a partial migrant. In mild winters, the old birds sometimes continue to frequent the trees or buildings where they nest. Their food consists almost entirely of earthworms, snails, insects and their larvæ, with an occasional seed or berry; but these form the exception. In autumn they congregate in immense flocks, which repair night after night to the same roostingplace. These flocks begin to assemble as soon as the first broods leave their nests, and go on increasing with successive broods till they are, later in the season, joined by old birds also. Early in the morning they disperse to their feeding-grounds, again to return with the setting sun to their chosen resting-place.-T. Southwell.

COLLECTION CATALOGUES.-I observe, among the advertisements in SCIENCE-GOSSIP, an announcement of the publication of a printed form of catalogue, prepared by Mr. Harting. It is no doubt a useful plan, but it does not fully explain itself. Will some one who has experience in cataloguing explain how he would set about to make a catalogue of a collection of say 2,000 botanical specimens, supposing that the specimens have already the necessary particulars attached to each, but not collected in a book, and that the collection is still rapidly increasing in all departments, phanerogamic and cryptogamic? It is easy enough to write out a catalogue of a completed collection, either alphabetically or in the order of classification; the difficulty lies in dealing with the additions, so as to avoid future confusion. Is there any better plan than the day-book and ledger; that is, to enter every addition consecutively in one book, with a consecutive number to each, and afterwards post them into a fully classified catalogue? This plan is cumbersome and slow.-F. T. Mott.

DOES GAS-LIGHT KILL PLANTS ?-I should be glad if some of your able correspondents would inform me whether gas, or the gas-light, kills plants? It is commonly supposed it does, but I should think wrongly, as the gas given off must form nourishment rather than otherwise.-E. T.

MITES. A neighbour last summer requested the writer to inspect his daughter's house, as it was, especially the drawing-room, which had been lately newly furnished, infested with a very minute species of mite. So extreme was the nuisance, that the maker of the furniture had been sent for from a town a long way off to examine it, and even

an action seemed not unlikely. Though the little pest was scarcely visible to the naked eye, the edges of the moreen curtains, the chair-bottoms, the insides of the piano and chiffonier, as well as other parts of the house and furniture, were quite white with them. I recommended the best means I could think of to destroy them,-ventilation, brushing, fumigation with sulphur, the use of carbolic acid, &c. The only other way, besides through the medium of the furniture, in which they were suspected to have been imported, was in a box of figs. The acarus was extremely hairy, pointed in front, and gibbous behind; but I send mounted specimens, which may be given to anybody who takes an interest in the mites.-R. G.

LESSER PETTYCHAP, OR CHIFF-CHAFF (Sylvia hippolais).-The early appearance of this lively little warbler is recorded on p. 93, by Mr. Westropp, who noticed it on March 9th. Six days later it was chirping in a shrubbery close to this house. Now, are there not good grounds for believing that this little bird does not migrate, since it has shown itself able to bear the severe frosts and heavy snows which prevailed since its arrival? It stays later than the other small emigrants, for I heard it in the woods last year so late as the second week in October. I am no believer in the hybernation of birds, but I have long had an idea that this species does not leave this country at all, but retires in winter to sheltered spots in woods, where it picks up a subsistence from the trunks and branches of trees, like the tits and other small birds. The disuse of its song, and its small size, would render it very unlikely to be noticed by ordinary observers. While on the early appearance of birds of passage, I may state that the Blackcap (Curruca atricapilla) has been in full song here since the 30th of March, and that I noticed three sand-martins (Hirundo riparia) about their old haunts the following day.-W.H. Warner.

PASTE EELS.-With some others I have often been troubled to procure these creatures, though carefully following the directions of the books. At others, I have found them abundantly in paste which has been put away and not touched. I have often seen it stated that some peculiar ears of corn, when soaked a short time, will abound with eels in the grains; and if so, may not the difficulty some persons find in getting them, proceed from the flour not having any of these particular corns ground up with it? As to their "spontaneous generation," I believe they are generated one from another, as is evident in the eggs and young ones.-E. T. S.

PASTE EELS.-I have tried "F. K.'s" plan for obtaining 4. glutinis several times, and I have not succeeded once. The following is a better (at any rate cleaner) way of preserving them when they appear than "F. K.'s." I copy it from Dr. Jabez Hogg's work on the microscope. He says: "The best means of securing a supply for any occasion, consists in allowing any portion of a mass of paste in which they show themselves, to dry up, and then lay it by for stock; if at any time a portion of this is introduced into a little fresh-made paste, and the whole kept warm and moist for a few days, it will be found to swarm with these curious little worms."W. Sargant, Junior.

PASTE EELS.-My little random shot has induced "F. K." to shelter himself behind Mr. Pritchard, and thus brought me face to face with a giant; but the little wrigglers in question, having been my occasiona.

pets for more than forty years, I may, perhaps, be allowed to indulge a little obstinacy in holding my opinion still. I am compelled to notice this subject again, because "F. K." has become catechist. I leave my unknown questioner to guess for himself, assuring him, at the same time, that my little scraps of scientific knowledge induce me to attribute Apostolic succession" alike to cats, rats, mice, and Paste Eels; and to the belief that there is a much greater difference between "Paste Eels" and Wheat Eels" than there is between a sheep and a goat.-A. Nicholson.

THE ERMINE IN NORTH WALES (p. 71).-Your correspondent "W. P.” is, it seems, unaware that the Ermine is in reality the Stoat in its winter dress. This animal, like the Scotch or varying hare (Lepus-variabilis), turns white in winter. The change from brown to white is more apparent in Northern Europe, but I have myself seen a specimen of the Mustela erminea hanging up in a wood here which was quite white, except a tinge of brown along the back. The M. erminea, whether in its summer or winter dress, whether as a stoat or an ermine, may easily be distinguished by the tip of the tail being always black.-W. H. Warner.

THE ERMINE.-I believe the cause of the confusion is that the majority of stoats do not, in this comparatively mild climate, fully change their coat in winter. They are seldom pure white.-G. E. R.

THE ERMINE IN NORTH WALES (p. 71).-It would seem probable that the discrepancy in question may be due to the comparative mildness of our climate, and the exceptional mildness of the past winter. It appears quite certain that the change observed in the fur of our stoat, the Mustela erminea, is a result of the effect of severe cold. As a boy I was familiar with the Stoat in farms at the south of England, but I never met with it in what is called its winter coat. The finest ermine comes from northern latitudes. If all our stoats were found to produce the fur called ermine in perfection, no doubt we should cultivate the trade for our home market.-A. H.

RATS AT ST. HELENA.-A gentleman who has passed many years of his life at St. Helena, told me lately several stories about rats, so curious that I thought them worthy of record. He said that at one time the common brown rat was extremely common all over the island, in fact, a perfect pest; and to avoid its attacks his father had constructed a large store, rat-proof; i.e., a rat once in could not get out again. A number, however, came in with produce and goods from the ships, and bred there. Around this store were venetian blinds to the windows, and one day one of his men, when it was raining, watched a rat sitting on the venetian, and putting out his tail to collect on it the drippings of water at the edge: he then withdrew it and licked it. The servant told his master, who immediately understood that the rats could get no water inside the store, and therefore directed that a butter firkin should be cut down to four or five inches, and in the top a large circular wire rat-cage trap should be fixed. Several small planks were placed for the rats to get up to the entrance to the cage, which exactly fitted the firkin. No food would have induced the rats to enter the trap, but water did, and many were thus captured. When caught they were given to the dogs; but there was one rat which would not leave the trap for many days. He

was well identified day by day, till, becoming incautious, he leapt down, and was immediately killed. There is one peculiarity with these rats, viz., their very often building or making their nests in the trees. I have in India several times found rats' nests in trees; but then they have always been stolen nests, such as deserted abodes of the squirrel or sparrow; but here my friend, who is no naturalist, tells me that they construct them principally of fir spines, on the ends of the boughs, some twelve or fifteen feet from the ground, in the common fir-trees. The spots selected are just where the overlapping bough nearly meets the lower one. He said that all know the rats' nests, and that he had seen them fired at, when many rats were killed, and fell out to the ground. He could tell me no more, and I think that, if original nests, as he held them to be, some grass must be woven in during their construction, as fir spines have but little power of cohesion. The situation of these nests was worthy of notice, although there is scarcely a situation where a rat's nest has not been found.-C. Horne, F.Z.S.

GRYLLUS VIRIDISSMUS.-I am sorry I cannot at present render much assistance to “E.Á. M.” (p. 59). I have occasionally kept these large green grasshoppers for a few days: they never voluntarily attempted to eat anything; but when a fly, stuck on the point of a needle, was held near the mouth, they would readily take and eat it. If possible, next summer I intend to study this insect more minutely: the larva is very pretty, and a brighter green colour than is the perfect insect.-C. G. R.

LIPARIS DISPAR.-At p. 69 Mr. Laddiman expresses a desire for information respecting this insect. I have reared several broods ("in-and-in "); in 1870 my moths were very fine, most of them, both males and females, were as large as those figured by Mr. Newman. I have this day carefully measured a female in my collection, and find it to be, from tip to tip of the expanded wings, two inches and three-quarters, which is exactly equal to the figure in "British Moths." Measuring a male in the same manner, I find he exceeds Mr. Newman's by one-twentieth of an inch. Last summer my L. dispar were not so fine, but I believe this was owing to the unfavourable season, as several other species were comparatively small. I have not met with much variety in L. dispar; the principal variation consists in the general ground-colours, most observable in the female, some being of a creamy, while others are of an ashy-white tint, with the blackish wavy lines more or less developed. Although my moths were not so large, they were well marked last year, and the males displayed more variety than usual, the upper wings of some approaching to a sandy-brown colour, and others were quite dark or cinerous. I have a few eggs of L. dispar to part with. If Mr. Laddiman or Mr. Henderson would like to have some of this strain, I shall be most happy to oblige them. The Editor has my address, and will kindly furnish it if required.C. G. R.

HOW TO STOCK A POND.-Will one or other of your experienced readers give me some hints for stocking with fish a newly-made lake of water consisting of about two acres? The depth averages 2 feet 9 inches, with several holes of deeper water. The bottom is gravelly. There is a constantly running spring, but not very rapid. What fish should I put in with a view to angling? Would it be any use to try trout? Where should I obtain a supply of fish for the purpose ?-F. C.

NOTICES TO CORRESPONDENTS.

E. W.-The larva is that of Meloë angusticollis. For a full account of this and other parasites on the bee, see article in SCIENCE-GOSSIP for 1870, pages 2 and 3, entitled "The Parasites of the Honey Bee," by Dr. A. S. Packard.

ENQUIRER. We have received the piece of gummed paper said to contain specimens of mites. We do not undertake to name specimens unless sent in a fit state for examination. We cannot ask those gentlemen (all of whom are authorities in their special departments) who kindly undertake to assist us, to prepare specimens for examination. It is also necessary that the sender should furnish us with all the information as to habitat, &c., he is able to give. We are always anxious to assist the student in natural history, but he must also put his own shoulder to the wheel.

L. T.-The moss is the commonest that grows, the Screw Wall-moss (Tortula muralis).

NEW SUBSCRIBER.-Answer next month. IGNORAMUS.-The small larvæ cases found on espalier apple-tree are those of Coleophas anatipennella.

A. L., Scarborough.-You will find Stark's "British Mosses" (Lovell Reeve & Co.), price 7s. 6d., a capital introductory book to the study of mosses, containing a good number of coloured illustrations.

R. DE L.-The jelly-like substance adhering to leaves is probably the ova of some species of shell-fish, perhaps of Limnea. It is not the common stickleback, which builds a nest.

RICHARD SMITH, Belper.-Tissues may be placed in the carmine staining fluid as soon as cut, unless maceration in glycerine is requisite to soften them. You will find all the information required for staining the various tissues in Dr. Beales's "How to work with the Microscope."

UNSCIENTIFIC ASTRONOMER.-There is a society called the "Observing Astronomical Society," different from the Royal Astronomical Society. The Hon. Secretary's name is William F. Denning, from whom all information may be obtained. -Address Messrs. Wyman, 74, Great Queen Street, London. A. H. A., Liverpool.- The Poduræ in the piece of wall-paper are Achorutes purpurescens, common in damp places.S. J. Mcl.

B. E. F.-Mineralogy is now included as part of chemistry, rather than of geology, as was formerly the case. There can be no doubt that the connection between the two former is far more natural, although mineralogy is of great service to the geologist, especially in his lithological investigations.

Roy. You will find a full account of the natural history position, functions, and habits of the sponges in Nicholson's "Advanced Text-book of Zoology," or in the "Manual of Zoology," vol. i., by the same author.

A. SMITH.-The parcel of grass sent is the Sweet-scented Vernal Grass (Anthoxanthum odoratum). It is the presence of this grass which gives the well known scent to newly-mown hay.

A. J. D.-A capital chapter on "Mimicry" will be found in Wallace's "Contributions to the Theory of Natural Selection." Bates first broached the doctrine in his "Naturalist on the Amazon." See article in last number of the Entomological Magazine on mimicry in insects.

J. B.-Hypnum commutatum: a little Anodus will be acceptable.-R. B.
