50 A Correct Colour Code. [Sess. 
of Sclater, and two Realms—Arctic and Antarctic—showing the applica- 
tion of my Code and of the method of engrafting the Sub-regional Colours 
on the map. 
A map on Mercator’s Projection by Mr Bartholomew, in black and white 
only, for use in colouring the geographical distribution of any genus or 
species, for object-lessons in a school or museum show-case—as already 
utilised in the Museums of London, Leeds, Edinburgh, and elsewhere—or 
for general purposes of illustration.* 
16. And lastly, a pamphlet-case made to my order by Hugh Stevenson & 
Sons, box-makers, &c., Ardwick, Manchester, which more than any other 
in the market combines strength, utility, and endurance with its moderate 
cost—about 4d. each—backed in buckram (Winterbottom white buckram 
No. 1), with rings, and patent hinging, and metal-protected edges. 
And now let me say that the great trouble I have ex- 
perienced in preparing this paper and suggested Code has 
arisen from my endeavours to amalgamate all the trades men- 
tioned. This part has occupied much time, attention, and 
correspondence, for nearly twelve months. Should my Code 
find favour in the eyes and minds of those who are devoting 
attention to bibliographical matters, to be reported to the 
British Association and the Royal Society, I think it is only 
on my part due to the tradesmen who have assisted me to 
give here a list of their names and addresses. I am sure they 
had as much trouble practically as I had theoretically, and 
from me they have derived little monetary reward :— 
Col. Logan, Stoneywood Paper Works, Denny (John Collins & Co.), for 
papers matched to Code in Manillas. 
Messrs Winterbottom, book-cloth manufacturers, Manchester, for two 
sets of superior buckrams, art linens, canvases, &c., and thinner 
cloths, &c., for “laying on” in bindings to order. 
Aspinall Enamel Co., for enamels to match Code Colours, and much 
trouble taken to do so, which colours they now keep in stock as 
“CCC Colours.” 
Messrs Hunter & Sons, bookbinders, 28 Queen Street, Edinburgh, who 
will bind to Code. 
Mr Wilson, bookbinder, Castle Hill, Edinburgh, for much trouble taken, 
and for set of thumb-index volumes for regions in Code Colours. 
The Zurich-Strasse “ Concilium Bibliographicum, &c.,” for the L. B. card- 
catalogue of vertebrata, 1896. 
Mr E. Bidwell, for helping me in the matter of cutting guide-cards to 
patterns of Code Colours exhibited. 
To Mr J. Bartholomew, who saw all my Code materials, and has adopted 
1 These maps might be made of various useful sizes, such as octavo, quarto, 
and folio, or even of smaller sizes for book-illustration purposes.
