CHEAP OIL Paints,. 259 



rable eomposition for the defence and preservation of all work 

 exposed to the inclemency of the weather, I have now the sa- 

 tisfaction of laying before the Society for the Encouragement 

 of Arts, &,c. specimens of some of the above colours ready pre- 

 pared for use, which will, I flatter myself, be found superior 

 to all others, for cheapness and durability, equal to any in 

 beauty, and not subject to blister or peel off by the snn. 



The vehicle made use of for the said paints is fish-oil, the The vehicle is 

 preparation of which is so simple, that when known, gentlemen ^'"°' * 

 who have large concerns to paint, may have this composition 

 of any colour manufactured, and laid on by their labourers. 

 I have sent a bottle of the prepared oil ; also, a number of 

 patterns, of various colours. The highest price of any, does 



not exceed th^ree-pence per pound, and many of them so low and is very 



as two-pence, in a state fit for use, I have likewise sent a <?h'^''^P' 

 pot of white-lead which has been ground with prepared fish- 

 oil, and which, when thinned with linseed-oil, surpasses any 

 white hitherto made use of for resisting all weathers, and rcr 

 taining its whiteness. I hope ray humble endeavours will merit ' 

 the approbation of the Society, before whom, I will, at any 

 time they shall please to appoint, make the various experi- 

 ments they may require.
