As Wat Tyler's insurrection was in 1381, the fourth year of Richard II., and as that was the year wherein the old mayoralty seal was destroyed, and the present seal made, our obliging correspondent, S. G., deems it "a very reasonable opinion, which many authors have entertained on the subject, that the dagger in the city arms was really granted at that period, in commemoration of Walworth having given Tyler the blow with that instrument, which was the prelude to his death." He says it is also further confirmed by the act of the assembly [the common council], which Maitland quotes [after Stow], inasmuch as one reason which appears to have been urged by them for destroying the old seal was on account of the same, at that time, being unbecoming the honour of the city, which, no doubt, referred to the addition of the dagger, which had then lately been made to the arms: and it likewise goes on further to state, in reference thereto, "that beside the images of Saint Peter and Paul, was placed the shield of the arms of the said city well engraved."

Our correspondent, S. G., will not conceive offence at a notion which varies from his own opinion; and probably, on reperusing the quotation from Stow and the following remarks, he may see some reason to abate his present persua

sion.

As a reason for the old seal, in the fourth year of Richard II., having been ordered by the common council to be broken, Stow says it was "very small, old, unapt, and uncomely for the honour of the city." His description seems to set forth its diminutive size and age, its "being very small, old," and "unapt," as the ground whereon they deemed it "uncomely for the honour of the city," and therefore caused the old seal to be destroyed, and a new one to be made. So far this appears to have been Stow's view of the matter; and should his authority be regarded, our friend S. G. may appear to have too hastily assumed that the common council order for the destruction of the old seal, as "unbecoming the honour of the city, no doubt referred to the addition of the dagger which had then lately been made to their arms.' Unless Stow's testimony be disputed, it may not only be doubted, but positively denied, that the dagger "had then lately been added to the city arms." Stow

speaks of it as a common opinion," when he wrote, that upon Walworth's striking Wat Tyler with his dagger Richard II. therefore "added a sword, or dagger, for so they terme it," he says, to the city arms; "whereof," he adds, "I have read no such record, but to the contrary." Then he takes pains to relate why the ancient seal was destroyed, and having stated the reasons already cited, he says, "this new seale," the seal now before us, "seemeth to be made before William Walworth was knighted, for he is not there intituled Sir, as he afterwards was." Afterwards comes Stow's conclusion upon the whole matter: "Certaine it is," he says, "that the same new seale then made, is now in use, and none other in that office of the maioralty: which," mark his words, "which may suffice to answer the former fable, without shewing of any evidence sealed with the old seale, which was the crosse, and sword of St. Paul, and not the dagger of William Walworth." What Stow here calls the "former fable," was the " common opinion" stated by himself, "that king Richard added to the arms of this city (which [in the notion of those who entertained the opinion] was argent, a plain cross gules) a sword, or dagger." That the city arms before the time of Richard II. was merely "argent a plain cross gules," Stow clearly treats as a vulgar assumption, "whereof," he says, "I have read no such record, but," and these following words are most notable," BUT to the contrary." This, his declaration " to the contrary" being followed by his particulars, just laid before the reader, concerning the present seal, Stow says, “may suffice to answer the former fable, without showing of any evidence sealed with the old seale:" that is, without showing or producing any document or writing "sealed with the old seale, which," to clench the matter, he positively affirms, "was the crosse, and sword of St. Paul, and not the dagger of William Walworth."

The cathedral church of the city of London is dedicated to St. Paul, who suffered martyrdom by the sword, and "the old seale," related by Stow to have been destroyed, he says, 66 was the crosse, and sword of St. Paul." It therefore represented the present shield of the city arms, which, on Stow's showing, existed before the time of Wat Tyler's insurrection, and are therefore" the crosse, and

sword of St. Paul, and not the dagger of written in 1561 to the council of Gorlitz William Walworth."

to

To the communication with which the liberty of differing has been taken, in furtherance of its object to elucidate the arms of the metropolis, our respected correspondent S. G. adds, " The origin of the seal may no doubt be traced to the source from whence sir Henry Englefield, in his walk through Southampton, derives the seal of the city of Winchester; in speaking of which his opinion appears be,that it was first used in consequence of an act passed for the benefit of merchants, in the reign of Edward I., which was afterwards greatly extended by the statute of Staples, passed in the 27th year of the reign of Edward III., whereby it was enacted that the commerce of wool, leather, and lead should be carried on at certain towns, called Staple towns, of which several are not seaports-but to each of these inland Staples a port is assigned for entries. It was also further enacted, that in each Staple there should be a seal kept by the mayor of the Staple."

In relation to this seal, Maitland sadly blunders. He says, "The ancient seal of this city having been laid aside in the fourth of Richard II, the present, whereof the annexed is a representation, was made in the same year, 1381." Then he annexes his " representation," purporting to be of this seal, which Stow so accurately describes, but, strange to say, he substitutes the "representation" of a seal wholly different. (See his History of London, edit 1772, vol. ii. p. 1193.) It is astonishing that Maitland should have so erred, for (in vol. i. p. 138) he describes the seal almost in Stow's words, and sufficiently at length to have saved him from the palpable mistake.

at Breslau: it is sealed in three places with beautiful red wax. There are two letters in 1563 from count Louis of Nassau to the landgrave William IV.; one dated March 3, is sealed with red wax, the other, dated November 7, is sealed with black wax. In 1566 are two letters to the rheingrave Frederick von Daun, from his steward Charles de Pousol, in Picardy, dated respectively, September the 2d, and September the 7th; another from Pousol to the rheingrave, dated Paris, January 22, 1567, is sealed with red wax of a higher colour and apparently of a coarser quality. On the 15th of May, 1571, Vulcob, a French nobleman, who the year before had been ambassador from the king of France to the court of Weymar, wrote a letter to that court sealed with red wax; he sealed nine letters of a From an prior date with common wax. old expense book of 1616, in the records of Plessingburg, "Spanish wax," and other writing materials, were ordered from a manufacturer of sealing-wax at Nuremburg, for the personal use of Christian, margrave of Brandenburg.

It has been conjectured that, as the oldest seals came from England and France, and as the invention is called "Spanish wax," it originated with the Spaniards; but this is doubted. The first notice of sealing-wax occurs in a work by Garcia ab Orto, or Horto, entitled "Aromatum et simplicium aliquot historia, &c." first printed in 1563, and afterwards at Antwerp in 1574, 8vo., in which latter edition it is mentioned at p. 33. oldest printed receipt for sealing-wax is "Neu Titularbuch, in a work entitled &c., Durch Samuelen Zimmerman, burger zu Augspurg 1579," 4to. p. 112. The following is a

"To make hard sealing-wax, called Spanish wax, with which if letters be sealed they cannot be opened without breaking the seal-Take beautiful clear resin, the whitest you can procure, and melt it over a slow charcoal fire. When it is properly melted, take it from the fire, and for every pound of resin add two ounces of cinnabar pounded very tine, stirring it about. Then let the whole cool, or pour it into cold water. Thus you will have beautiful red wax.

"If you are desirous of having black wax, add lamp black to it. With smalt, or azure, you may make it blue; with

white lead, white; and with orpiment, yellow.

"If instead of resin you melt purified turpentine, in a glass vessel, and give it any colour you choose, you will have a harder kind of sealing-wax, and not so brittle as the former."

In these receipts there is no mention of gum lac, which is at present the principal ingredient in sealing-wax of the best quality. The name "Spanish wax," probably imports no more than "Spanish flies," "Spanish gum," and several other "Spanish" commodities; for it was formerly the custom to give all new things, particularly those which excited wonder, or excelled in quality, the appellation of "Spanish."*

Dutch sealing-wax, or wax with "brand well en vast houd," burn well and hold fast, impressed on each stick, was formerly in great repute; but the legend having been constantly forged was no security against imposition. The "best Dutch sealing-wax" usually sold in the shops of London, is often worse than that which inferior manufacturers stamp with the names of many stationers, who prefer a large profit to a good reputation. It is not an easy matter, in 1826, to get a stick of sealing-wax that will "burn well and

hold fast."

in common use." It should be observed, however, that every black pigment mixed with gum or size can be soon and easily washed out again with water.

It is not purposed to make this a "Receipt Book," yet, as connected with this subject, two or three really good receipts may be of essential service, at some time or other, to many readers. For instance, artists, and other individuals who require it, may easily manufacture a black pigment in the following manner, with a certainty of its being genuine, which can scarcely be placed in the article sold at most shops.

A pure Lamp Black.

Suspend over a lamp a funnel of tin plate, having above it a pipe to convey from the apartment the smoke which escapes from the lamp. Large mushrooms of a very black carbonaceous matter, and exceedingly light, will be formed at the summit of the cone. This carbonaceous part is carried to such a state of division as cannot be given to any other matter by grinding it on a piece of porphyry This black goes a great way in every kind of painting. It may be rendered drier by calcination in close vessels; and it should be observed that the funnel ought to be united to the pipe, which conveys off the smoke, by means of wire, because solder would be melted by the flame of the lamp.*

Receipts for Ink.

Chaptal the eminent chemist, after numerous experiments regarding writing ink, concludes, that the best ingredients and proportions are the following, viz: two parts of galls, in sorts, bruised, and one part of logwood chipped; these are. to be boiled in twenty-five times their hours, adding a little water from time to weight of water for the space of two decoction so made, he says, will comtime, according to the evaporation. The monly mark from 3 to 34 degrees upon the hydrometer of Beaumé, equal to about 1022 of the common standard. At the same time a solution of gum arabic is to be made with warm water, until

the latter will dissolve no more of the former. This solution will mark 14 or 15 degrees, equal to about 110. A solution of calcined sulphate of iron is also

* Tingry.

to be made, and concentrated so that it will mark 10 degrees, equal to about 1071. And to this as much sulphate of copper is to be added as will be equal to one-twelfth part of the galls employed to make the decoction. The several matters being so prepared, six measures of the decoction are to be mixed with four measures of the solution of gum; and to this mixture from three to four measures

of the metallic solution are to be added, by a little at a time, mixing the several matters each time by shaking. Ink so made, will, he says, form no sediment and he estimates the proportions of solid matters contained in it to be five hundred parts of gums, four hundred and sixtytwo parts of the extract of galls and logwood, and four hundred and eighty-one parts of metallic oxides.

Dr. Bancroft, who gives these particuIars from Chaptal, proposes the following, as being generally the most suitable proportions for composing the best and most lasting writing ink, viz:

Take of good Aleppo galls, in sorts, coarsely powdered, twelve ounces, and of chipped logwood six ounces; boil these in five quarts of soft water two hours, and strain off the decoction whilst hot; then put to the residuum as much boiling water as, when properly stirred, strained, and added to the former, will suffice to make the whole of the decoction equal to one gallon; add to this five ounces of sulphate of iron, with the same quantity of gum arabic, and two ounces of good dry muscovado sugar; let these be all dissolved, and well mixed by stirring.

A calcination of the sulphate of iron, which Chaptal, Proust, and some others have recommended, Dr. Bancroft does not regard as of much importance; for he says, though the ink may be thereby made to attain its utmost degree of darkness, almost immediately, yet the strong disposition which ink has to absorb oxygen from the atmosphere until saturated therewith, will enable it, without such calcination, to attain an equal degree of blackness, in a day or two, according to the temperature of the air, if the latter be allowed free access to it. For reasons which he also states, he omits the sulphate of copper; though he observes that, if any portion of that metal were deemed beneficial, he should prefer verdigrise to the sulphate, the latter containing a much larger proportion of acid than even the sulphate of iron, and being, therefore,

more likely to render the ink corrosive. He regards gum as highly useful to retard the separation and subsidence of its black part, or compound of colouring matter and iron, previous to its application to paper, as well as to hinder it, when used, from spreading and penetrating too far.

Indelible writing Ink.

oxygenated muriatic acid had been found M. Chaptal remarks, that, since the capable of discharging the colour of common writing ink, both from parchment and paper,without injuring their texture, it had been fraudulently employed to efface particular parts or words of deeds, contracts, or other writings, for which others had been substituted, leaving the signatures untouched. In consequence of these frauds, the commercial parts of society, as well as governments, were solicitous for the discovery of some composition, which might be employed instead of common writing ink, without its defects; therefore Chaptal, (being then minister of the interior of France, and possessed of great chemical science,) self particularly with that subject; and as might be expected, occupied himhe states, that up to the then present time, the composition which had been found most useful for this purpose, consisted of a solution of glue in water, with which a sufficient portion of lamp black and a little sea salt were intimately mixed, by rubbing them together on marble. This composition was made sufficiently thin by water, to flow readily from the pen; and he describes it as being capable of resisting the action, not merely of cold, but of boiling water, and also of acids, alkalies, and spirit of wine; and attended with no inconvenience but that of abrasion by being rubbed.

It is observed by Dr. Bancroft, that when lamp black has been incorporated with common ink, by first rubbing the former in a mortar with a mucilage of gum arabic, the writing done with it could not be rendered invisible by the application of muriatic acid; and, doubtless, such an addition of lamp black would hinder the letters from ever becoming illegible by age, at least within any length of time which the paper and parchment could be expected to last. But ink made with this addition would require to be frequently shaken or stirred, as the lamp

black would otherwise be apt to separate and subside.

In the making of indelible ink, the receipt for lamp black before given may be of considerable importance.

Calico Printing.

Perhaps no object has more engaged "the ingenious chemist's art" than this, and leave is craved to conclude this diver sion from the mayoralty seal of London, by what may be serviceable to some who are actively engaged in an extensive branch, from whence our private chambers, and the dresses of our wives and daughters, derive continual improvement. Prosubstantive, or Chemical Black, for Calico Printers.

"Some years ago," says Dr. Bancroft, "I purchased of a calico printer, possessing great knowledge of the principles and practice of his art, the secret of a composition which he had employed with success, as a prosubstantive black, and which, as far as I can judge from experiments upon a small scale, deserved the high commendations which he bestowed upon it: and though I have never obtained the smallest pecuniary advantage from this purchase, in any way, I will here give the full benefit of it to the public. The following was his recipe, with some abbreviations of language: viz. Take two pounds of the best mixed galls, in powder, and boil them in one gallon of vinegar, until their soluble part is extracted, or dissolved; then strain off the clear decoction, and add to the residuum of the galls as much water as will be equal to the vinegar evaporated in boiling; stir them a little, and after allowing the powdered galls time to subside, strain off the clear liquor, and mix it with the former decoction, adding to the mixture six ounces of sulphate of iron; and this being dissolved, put to it six ounces more of sulphate of iron, after it has been previously mixed with, and dissolved by, half of its weight of single aquafortis; let this be stirred, and equally dispersed through the mixture, which is to be thickened by dissolving therein a sufficient quantity of gum tragacanth, (of which a very small proportion will suffice.) Calico, after being printed or pencilled with this mixture, should, when the latter is sufficiently dried, be washed in lime water, to remove the gum and superfluous colour, and then either streamed or well rinsed in clear water. This composition

has not been found to weaken, or injure, the texture of calico printed or pencilled with it, and the colour is thought unob jectionable in regard to its blackness and durability."

It is added by Dr. Bancroft, that when sulphate of iron is mixed with aquafortis, the latter undergoes a decomposition; the oxygen of the nitric acid combining with the iron, and raising it to a much higher degree of oxidation; the result of these operations is the production of a fluid which has the consistence and smooth appearance of oil, and which (though the name may not be quite unexceptionable) I will call a nitro-sulphate of iron. I have been induced to believe, from several trials, that a better prosubstantive black than any other within my knowledge may be formed, by taking a decoction, containing in each gallon the soluble matter of two pounds of the best galls, in sorts, and when cold, adding to it for each gallon twelve ounces of sulphate of iron, which had been previously mixed with half its weight of single aquafortis, (of which one wine pint should weigh about twenty ounces,) and, by the decomposition just described, converted to the nitro-sulphate of iron just mentioned. By thus employing twelve ounces of sulphate of iron, oxygenated by nitric acid, instead of six ounces of the latter, with six ounces of the green sulphate in its ordinary state, an improvement in the colour seems, by my experiments, to have been invariably produced, and without any corroding or hurtful action upon the fibres of the cotton."

With these scientific receipts and suggestions it may be agreeable to close. Matters of this kind have not been before introduced, nor is it purposed to repeat them; and those who think they are out of place at present, may be asked to recollect whether any of themselves ever obtained knowledge of any kind that, at some period or other, did not into use?
