3d KIND. Colours of various shades. One invariable, the 
white ; the other unique, pie-bald. 
4th KIND, Colours of three shades. One unique, roan . 
So that, on the whole, there are two classes, five kinds, and 
thirteen varieties. As to shades of varieties, they require no 
pointing out. 
The Particularities of colour are arranged in eight prin- 
cipal divisions as follows : 
1st DIVISION. — Particularities resulting from difference of 
shade of the same colour : such as silvery , golden, &c. 
2d DIVISION. — Particularities resulting from the absence or 
presence of white hairs : these are either whole-coloured or 
speckled, with marks about the head, bald-faced, white-legged, & c. 
3d DIVISION. — Particularities as regards black hairs : such 
as black-headed, patches or spots, & c. 
4th DIVISION. — Particularities of hay hairs : red-speckled, 
flesh-coloured spots, bay mule-striped, &c. 
5th DIVISION. — Particularities arising out of mingled hair 
of a different shade from that of the coat : such as the dappled, 
the marbled, &c. 
6th DIVISION. — Particularities depending upon the direction 
of the hairs. 
7th Division. — Particularities dependent upon the colour of 
the skin. 
8th Division. — Particularities, natural or accidental marks : 
such as wall-eyes, chestnuts, tumours or lumps, warts, slit ears, 
tail long or docked, & c., blemishes, scars, &c. 
Such constitutes a summary outline of M.Yiger’s description. 
Simple as the sketch is, it will enable us to at once understand 
the principle of co-ordination upon which his work has been 
composed, and the disposition and methodic arrangement of the 
numerous materials classified together in it. 
The Committee appointed by the Society to examine this 
paper, report upon it as above. At the same time, they add, 
that its detail, so far, contains no more than has for years past 
been taught in the Alfort Veterinary School, in proof whereof 
they subjoin a summary of the Lectures given on the same sub- 
ject, by M. Rigot ; which, since it is a branch of knowledge paid 
but little attention to in our own country, we shall transcribe : — 
The colours are divided into simple and compound. 
The Simple Colours, which resolve themselves into four 
kinds, comprise within themselves several varieties. These
