$dly, When the picture is dry, it is put near the 
fire, whereby the wax melts, and abforbs all the co- 
lours. 
It muft be allowed, that nothing can be more Am- 
ple than this method ; and it is thought, that this 
kind of painting is capable of withfianding the inju- 
ries of the weather, and lafis longer than paintings 
in oil ; which I will not anfwer for. 
The effedt produced by thefe colours upon wax 
is very Angular ; nor can one have any notion of it 
without feeing it. The colours have not that natural 
varnifii or Alining that they acquire with oil ; but 
you are capable of feeing the pidture in any light, 01- 
in whatfoever Atuation you place it : in fiiort there 
can be no falfe glare or light upon the pidture for the 
fpedtators : the colours are fecured, are firm, and will 
bear wafiiing ; and have a property, which I look 
upon as the moA important of any, which is, that 
they have fmoaked this pidture in places fubjedt to 
foul vapours, and to fmoke in chimnies ; and then 
by being expofed to the dew, it became as clean, as 
if it had been but juA painted. 
This, Sir, is all that regards the new cncanfiic 
painting or painting in burnt wax : it comes from 
the word encaufhun , which is all that remains about 
it : for the ancients have commonly left us the 
names of their difcoveries, without any account of 
them.
