is given under his name, for it could not be worked with, any more than Moxon's, FertePs, Breton's, or Papillon's, for the reasons I have stated when treating on their methods; in fact, it appears to me to be the copy of a memorandum that he had made of the old method of making Ink, similar to some of those which I have given.

respect. The design of adding the bread and onions is more effectually to destroy the greasiness; but Dr. Lewis doubts, whether additions of this kind are of much use. They then boil thirty or thirty-five pounds of turpentine apart, till such time as they find, upon its cooling on paper, that it breaks clean, like glass, without pulverizing, for it it pulverise easily, it is a sign that it is burnt. The oil and turpentine being thus prepared, the first is gently poured, half cold, into the latter; and the two stirred together with a stick till they be well mixed: after which the boiling is repeated and the composition is set by, to lie used occasionally. The turpentine is used in order to give a greater body to the varnish, and to increase its drying quality ; and with some artists, litharge has in this intention been a secret. M. de Breton, in the Encyclopedic, observes, that when very old oil is used, neither turpentine nor litharge are needful ; but that when the oil is new, some turpentine ought to be employed, because, without it, the smearing of the paper, by the spreading or coming off of the ink, cannot be avoided ; and he adds, that it is much more eligible to use old oil than to have recourse to this correction of the new; both turpentine and litharge, particularly the last, making the mixture adhere so firmly to the types, that it is scarcely to be got entirely off by the ley, whence the eye of the letter is soon clogged up.

" Now to proceed to make ink, they take a quantity of this mixture, and add to it a certain quantity of lampblack, working it up with a kind of wooden mallet, or brayer, till the whole be incorporated, and reduced into a kind of putp, which is the ink for use.

work very foul, and daub the types to a great degree. The same thing will happen from using too much black, at the same time that both the soap and black hinder the Ink from drying; while too much oil and rosin tear the paper, and hinder it from washing off.—The following receipt has been found to make Printing Ink of a tolerable good quality.

" Take a Scots Pint of Linseed Oil, and set it over a pretty brisk fire in an iron or copper vessel capable of holding three or four times as much. When it boils strongly, and emits a thick smoke, kindle it with a piece of paper, and immediately take the vessel off the fire. Let the
