44 A Correct Colour Code. [Sess. 
Of Keillor’s work we need not speak here, as its aims and 
objects are, like most of the others, distinctly for descriptive 
purposes. But Professor Camerano’s paper, referred to by 
Beddard in his ‘ Zoo-geography’ (1895, p. 118), which, un- 
fortunately, I have not seen in its entirety, first, I believe, 
makes the attempt of applying suitable standards of colours 
for zoo-geographical purposes. Not having seen this treatise, 
I cannot say whether his applications of his colours are more 
suitable, more natural, from topographical standpoints, than 
the one I am about to propose. Nor can I, therefore, place 
his and mine in parallel columns for purposes of comparison. 
So far I take what I can gather from Beddard’s analysis (loc, 
cit., p. 118): “Graphic Methods of representing the facts of 
Distribution.” “The colour might even be made to some 
extent appropriate ” (Joc. cit.) Then he quotes Camerano :— 
Yellow, prevailing colour in Africa. 
Grey, " " Asia. 
—and so forth. “ And,” continues Beddard, ‘“‘ Mobius colours 
the ‘ Transitional Tracts’ (Heilprin’s) with a paler tint applied 
to the region which they most resemble.”  Heilprin prefers to 
shade the transitional areas, and then Beddard destroys this 
idea. 
Now, the colours I have selected are, as I have said, the 
primary, secondary, and tertiary colours of Hay’s nomen- 
clature, with the addition of white, grey, and black. These 
last mentioned are added by me because of a convenience 
which will become apparent as I proceed. To recapitulate, 
my Code Colours are— 
1. White. 4. Red. 7. Green. 
2. Grey. 5. Yellow. 8. Purple. 
3. Black. 6. Blue. 9. Orange. 
10. Russet, 07 Brown, or both. 
The above colours I offer as an EyE-InpEXx, by which 
attention may be directed to the books or pamphlet-cases 
upon the shelves of any library; so that these applied to 
Realms, Regions, and Sub-regions, may at once indicate the 
items in the library devoted to each. 
But, it may be argued, such an eye-index cannot now be 
applied to past accumulations of books, or at least to already
