TABLE III. 
Compound tints of the third order are not set down, it being unnecessary , 
as they are formed from Table II, exactly in the same manner as those are 
from Table I; and produce similar tints, only weaker. 
I shall only add, that in mixing these colours, the imperfections of the 
pigments -we have to use must be allowed for;'for they will all fall very far 
short of those seen in the Prismatic Spectrum; but I believe the following list 
will come as near as any: 
Gamboge 
Red-lead and Gamboge 
Vermillion and Red-lead 
Lake and Prussian Blue 
Prussian Blue 
Antwerp Blue 
Antwerp Blue and Gamboge 
for Yellow 
for Orange 
for Red 
for Violet 
for Indigo 
for Blue 
for Green
