following manner. Take twelve ounces, or three quartos of a 

 piut^ wine measure, of cold spring water, and four ounces and a 

 half of gum-arabic ; put them into a glazed earthen vessel, and 

 when the gum is dissolved, ad.l eight ounces of white wax. Put 

 the earthen vessel with the gum-water and wax upon a slow fire, 

 and stir them till the wax is dissolved and has boiled a few mi- 

 nutes : (hen take them off the fire and throw them into a bason, 

 as by remaining in the hot earthen vessel the wax would become 

 rattier hard ; beat the gum-water and wax till quite cold. As there 

 is but a small proportion of water in comparison to the quantity of 

 gum ind wax, it would be necessary in mixing this composition 

 with the colours, to put also some fair water. Should the compo. 

 sition be so. .made as to occasion the ingredients to separate in the 

 bottle, it will become equally serviceable if shaken before used to 

 mix with the colours. 



'* I had lately an opportunity of discovering that the composi- 

 tion which had remained in a bottle since the year 1792, in which 

 time it ha-1 ^ro\vn dry and become as solid a substance as wax, re. 

 turned to a cream-like consistence, and became again in as proper 

 a state to mix with colours as when it was first made, by putting a 

 little cold wati-r upon it, and suffering it to remain on a short 

 time. I also lately found somt' of the mixture composed of only 

 gum-arabic water and gum mastich, of which I sent a specimen to 

 the Society of Arts in 1792 ; it was become dry, and had much 

 the appearance and consistency of horn. I found, on letting some 

 cold water remain over it, that it became as fit for painting with 

 as when the composition wasfir^t prepared."

Painting of Paper Hangings. 



THERE are three methods of effecting this. The first by print, 

 ing on the colours ; the second by using the stencil ; and iho third 

 by lajing thm on with a prncil, as in other kinds of painting. 

 When the colours are laid on by printing, the impression is made 

 by wooden prints, which are cut in such a manner that the figure 

 to be expressed is made to project from the surface by cutting away
