COLOES KEQUIEED BY THE ZOOLOGICAL 
OR BOTANICAL ARTIST. 
Notwithstanding so great a variety of colors exist in 
Nature, especially in the animal and vegetable kingdoms, 
and that an almost unlimited number of pigments are 
manufactured for the use of artists, a comparatively very 
small number is really required. The author has in his 
collection considerably over three hundred water-colors, 
each bearing a different name, representing the produc- 
tions of the best makers (see page 16). Nearly three 
hundred of them are put aside, however, since very care- 
ful experiments have proved that they are superfluous. 
His working palette, selected from the above number, is 
limited to thirty-six colors, at least one half of which are 
used for convenience rather than because they are neces- 
sary. Following is the list, those most essential being 
distinguished by an asterisk (*). 
Black, 
*1. Lamp-Black. 
Browns. 
*2. Bone-Brown, or Bistre. 
*3. Eoman Brown (Schoenfeld's). 
*4. Eaw Umber. 
*5. Sepia.
