ing are yellow, as well as many other plants and parts of plants. 
The fruit of Ribes rubrum, or red currant, and the fructification of 
Lichen cocciferus are red. The flowers of Veronica saxatilis, E. B. 
tab. 1027', and alpina, E. B. tab. 484, are blue; and those of \. 
spicata, E. B. tab. 2, are full blue. 
Binaries and Ternaries are more universal. 
Colours are identically the same on any substance however re- 
flected, whether mineral, as from earthy or metallic ones; vegetable, 
as from flowers or fruit ; or animal, as from hair, feathers, &c. I'he 
same colours may be reflected very dully and afterwards be mixed 
by shade till lost in darkness, as may be readily understood if we 
colour different substances with the same yellow, red, or blue, such 
as paper, silk, velvet, or silver. 
I once thought of making more references to the three primi- 
tive colours in minerals, vegetables, and animals; liowever, as minerals 
are chiefly used, so they come of course in their places as material 
colours. Vegetables in Great Britain have good yellows, as most 
Banunculuses ; perfect blues are more scarce, and perfect reds 
also. I cannot find tliat we can refer to any British insect 
for yellow, red, or blue. The Rev. W. Kirby, author of the 
JVIonographia Apum Anglise, was so good as to point out some parts 
of insects, including some foreign ones, that would identify these 
colours very well, when the specimens are perfect ; but perhaps it 
might be aggravating to make these references, as something might 
be wrong. Birds and quadrupeds have the local colours in parts 
occasionally very brilliant. The scarlet Ibis is universally allowed 
to be so ; and D. Turner, Esq. in his Fuci, considers red as 
between crimson and scailet ; which seems to me to be perfectly 
correct. I need here say no more, but refer to the Chromatometer 
as the instrument or more perfect instructor when duly attended 
to ; and I have no doubt that by such attention reasonable ideas will 
become more general, and lead to improvement in the hands of some 
person who has a happy independent leisure, and abilities not only
