ON PAINTING WITH MILK. 213 



by rendering a material ufeful which in many places had, 

 properly fpeakiug, little value, unlefs in the ordinary ufe of 

 extracting the butyraceous part, which alone reprefented the 

 whole value of the milk before its decompofition. He has at 

 the fame time given a degree of perfection to this paint, by 

 rendering the procefs diffidently Ample, to afford a folid 

 colour, nearly without fm.cH and at a moderate price. 



Thefe qualities, which painting in milk really poffefles, ap- Improved procefs 

 pear to render it little fufceptible of amelioration. I fhali for P alntin &' 

 neverthelefs venture to propofe one which has fucceeded in 

 my hands, and of which the experiments have been made on 

 a fcale fufficiently extenfive to infure the goodnefs and the 

 value of the refults I have obtained. * 



-After having given an account of the obfervations which 

 led me to this procefs, I fliall fpeak of the materials I ufed, 

 their proportional quantities, the beft method of combining 

 them, and, in a word, the procefs to which we muftjuftly 

 apply the denomination of cheefe painting, f 



Citizen Cadet-de-Vaux, in his memoir on milk painting, Cadet-de-Vaux'e 

 has given two proceffes, which, as it appears to me, ought tW0 JK| * erf! 

 to be confidered as one, becaufe the firft which he announces tiquc on his mc- 

 as limilar to common diflemper does not differ from the thod * 

 fecond, which he gives as proper to be fubftituted inficad of 

 oil painting, except in the Burgundy pitch, which conflitutes 

 part of this laft. In fact, Burgundy pitch renders the colour 

 more folid, but it is far from rendering it capable of being 

 warned like oil paint ; a property which is known to be 

 truly charafteriitic of this paint, and is of itfelf fufficient to. 

 diftinguifh it from diflcmper. I fhail not, therefore, examine 

 thefe two proceffes feparately ; and I fliall conclude my ob- 



* I painted an entire chamber with the colour I fliall proceed to 

 defcrihe. Individuals, who flept in it the very day of the operation, 

 were in no refpecl: incommoded by the fmell of the paint, though 

 the door and the windows were fliut the whole night. 



•f We find, in the Diclionnaire de Peinture de Pernety, a note in 

 which he fpeak s of a pamphlet entitled, La Peinture au Fromage ou 

 au Ramekin. It was written in oppofition to the encauftic method 

 of painting, of which Citizen Bachelier has, as it were, re-invented 

 the procefs. I have not been able to procure this pamphlet, for 

 which I am very forry, as it might probably contain fome data re- 

 fpecling the method of painting on which wc at prefent treat in a 

 more fcrious manner.— D.
