FOEHN WINDS IN THE ANTARCTIC. During the Antarctic voyage of the Dis. covery, warm southerly winds were observed which, because of their high temperature, have generally been regarded as of foehn-like character. Sir Clements Markham (Geogr. Journ., June) believes that the high temperature may result from the fact that these winds blow from the ocean beyond the pole, that is, Weddell Sea, and not from adiabatic warming during descent. Hence he thinks that the Great Barrier may end on the other side of the pole with another line of ice-cliffs facing the Weddell Sea, and that the winds may blow across the ice barrier with great velocity without lowering their temperature. On the other hand, Dr. W. N. Shaw suggests that the snow which comes with these warm southerly winds is carried along in a surface drift, and notes that intensely cold air can contain very little moisture.

The Annuaire météorologique of the Royal Observatory of Belgium contains a useful list of text-books of meteorology, prepared by J. Vincent. Special attention is paid to general treatises, but a considerable number of special works on marine, medical and agricultural climatology are included. The list begins with Aristotle, and includes books in Latin, Greek, English, French, German, Italian, Dutch, Russian, Danish, Spanish, Hungarian, Norwegian and Portuguese.

TUE mechanism of the origin of rain-clouds. and the conditions of heavy rains and floods on the northern slope of the Pyrenees, were discussed by Marchand. Director of the Pic du Midi Observatory, before the Congrès du SudOuest Navigable, held at Bordeaux in June, 1902. The paper was printed in the proceedings of that congress, and a German translation of a portion of the article, in the Meteorologische Zeitschrift for June, 1905, makes this interesting study accessible to the general reader · RECENT publications on the meteorology of the free air are those of Teisserene de Bort, on the diurnal changes in temperature (Comptes rendus, Vol. cxl., 1905, 467) and of Hergesell, on the results obtained by means of kites over the Mediterranean Sea and Atlantic Ocean in 1904 (ibid., January 30, 1905).


LOW TEMPERATURE IN THE SAHARA. In the Meteorologische Zeitschrift for June, 1905, there is a note on some low temperatures observed on December 19, 1904, in the Sahara, between Tuggurt and Guerrara. The temperature at midnight was 30.20 Fahr: at daybreak (6:15 A.M.), 28.4°; at sunrise (7:15 A. .), 33.8°; at 2:30 P.M., in the shade, 75.2°; at 7 P.M., 41.0°; and at 8:30 P.M., 39.2°. It was calm, and the sky was clear. On December 20. at 7:30 P.M., the temperature was 33.8°, and there was heavy frost, which in places reached a thickness of 1 cm.

The annual report of the council for the year 1904-5 states that the arrangements for the meeting of the association in South Africa had been directed, under the sanction of the council, by a special South African committee, sitting in London, and consisting of the general officers of the association (the president and president-elect, the general treasurer and the general secretaries), Professor Armstrong, Dr. Horace Brown, Sir William Crookes, Sir

by the condition of the water, and inland, away from the influence of tide water, they do not breed until the ground beneath their nests is flooded. For this reason, although Mr. Cherrie stayed until June, he only obtained eggs of this bird. Eggs of a number of other species of birds were also obtained, many of which are but little known.

We learn from the New York Evening Post that the city of Nuremberg, in conjunction with the Society of German Clockmakers, has erected a monument by way of commemorating Peter Henlein, who, four hundred years ago, substituted springs for weights in clocks, and thus made watches a possibility. The statue was made by the Berlin sculptor Meissner. It represents Henlein at work in his shop.

In connection with the indication by the council of houses in London which have been the residences of distinguished individuals, a memorial tablet was on August 14 erected on

No. 34, Gloucester Square, Hyde Park, where Robert Stephenson, the great engineer, resided at one time. The tablet is of encaustic ware and terra-cotta in color.

Dr. Otto Herz, the entomologist of St. Petersburg. has died at the age of fifty-six years. The deaths are announced of the Rev. Dr. J. Keith, of Scotland, who took an active interest in natural history, and of Mr. W. E. Langdon, a past president of the British Institution of Electrical Engineers.

We recorded last week the death of Professor Leo Errera. A correspondent writes in regard to him: “Errera was one of the comparatively few rich men who work as hard at science as do those who earn their living by teaching and research. A multi-millionaire, he earned the rather hard degree of Docteur Agrégé, and since his student days has been an important factor in the class-room and research work in botany at Brussels. His most notable work as an investigator, perhaps, was his demonstration that fungi store food reserves in the form of glycogen, like animals, and the contributions from his laboratory have been chiefly along physiological and ecological lines. Notwithstanding this limit to the field of his more active contributions, however, he was interested in all branches of botany, and at the recent International Congress at Vienna, where he secured a decision to hold the next quinquennial session at Brussels, he was one of the most constant and interested attendants at the arduous--and perhaps thankless--nomenclature sessions.

Tue correspondent of the London Times in Cape Town cabled on August 18 that the first boat, conveying a portion of the visiting members of the British Association to Durban, and marking the conclusion of the business gram in Cape Town, would leave that night. It was obvious at the outset that a rivalry was established between the purely pedagogic portion of the program and that part which makes for first-hand knowledge of South Africa.
