1898-99. | A Correct Colour Code. 49 
No. 1 Colour,” which is coloured for purposes of the Code by Aspinall’s 
enamels. 
5. Aspinall’s Enamels, matching my Code, to order, and which colours the 
Aspinall Company keep in stock. 
6. A complete set of the colours used for Regions, and with all the com- 
binations used for the Sub-regions, and named on the backs of each slip of 
paper and of buckram. 
7. The Code Colours, matched by Winterbottom in buckrams, art linens, 
art canvases, for binding according to directions, each coloured cloth being 
numbered with Winterbottom’s colour numbers, a list of which I also give 
(infra) to facilitate orders. 
8. A bound series of volumes, with A B C thumb-indexes, in full colowrs 
of the Regions as assigned by my Code. (Wilson, binder, Castle Hill, 
Edinburgh.) 
9, Aspinall’s Enamels to Code.—I did not exhibit the cases of these 
colours supplied. But the colours were shown under 5 antea, as painted 
upon Winterbottom’s white buckram colour, No. 1. This can be used 
upon pamphlet-case backs—obliterated when the possessor comes to bind 
off sets in Winterbottom’s cloths, and repainted again in enamels. 
10. Winterbottom’s thinner cloths, “Cloth Extra”—Matched to Code 
for use, in laying on the Sub-regional Colours upon the stronger and more 
durable canvases and buckrams (No. 6) by bookbinders’ paste or Le Page’s 
fish-glue. 
11. A Parcel showing application of my Code Colours to use of 
“Library Bureau” or Zurich-Strasse Guide-Cards to Regions and Sub- 
regions. 
12. A specimen volume bound, showing—Buckram No. 1, with Aspinall’s 
enamel, label-fourth, meaning “ Wearctic-Arctic.” 
13. A specimen volume, roughly bound, showing — Buckrams No. 1, 
with thinner Winterbottom’s cloth (matched) laid on as Sub-regional label- 
fourth of back. 
14. An L. B. case (oak) which contains the Zurich-Strasse Card-Cata- 
logue of the papers on Vertebrata for 1896, having applied in it (roughly) 
my Colour Code Guide-Cards. 
15. A map by Mr Bartholomew, who adopts my Code in his next Zoo- 
geographical Atlas on Mercator’s Projection for colouring the six Regions 
1 The Regional Guide-Cards have the guide-top-edges full length of the Cards. 
(L. B. Card.) The Sub-regional Cards have projections “thrown upon” the 
longer cards in 7ths and 3rds. (L. B. Cards come in between.) It would be 
very desirable that Zurich-Strasse cards be cut by regular machinery according 
to this Code. The Library Bureau up to this time has declined to adopt this 
Code and arrangement for Guide-Cards—no doubt upon the ground of trouble, 
the expense of new uniform cutters, and the present uncertainty of any demand 
which would warrant such outlay. Should countries be desired for direct refer- 
ences, an alphabetical code can be easily applied, and letters stamped (or printed) 
on the L. B. cards between, or by using a greater quantity of the 7th and 3rd 
projections under each colour, and an alphabetical arrangement of the books 
or pamphlet-cases could be utilised upon the shelves.
