270 DR. E. CRISP ON THE ANATOMY OF THE GIRAFFE. [June 14, 
such animals as possess it. In the old Giraffe its length was nearly 
an inch. 
I inspected carefully the whole length of the intestinal tube. The 
glandular crypts at the origin of the duodenum, first described by 
MM. Joly and Lavocat, as mentioned in my last paper, were well 
marked; they consist of about thirty small sacculated crypts, their 
mouths varying in diameter from 3 line to 13 line. They partake 
much of the character of those found near to the cecal valve; and 
I think the term “crypt,” used by MM. Jolly and Lavocat in 
1846, is more applicable than that of “sacculated pouch,” employed 
by Dr. Cobbold. . In the small intestines I found three agminated 
patches ; it will be remembered that in the Giraffe two months old 
there was only one, and that of very small size. The longest of the 
patches in the present specimen was about 23 inches, and 4 an inch 
in width ; it consists of eight divisions, formed by the mucous mem- 
brane, and these are subdivided into smaller folds; they are all, 
however, superficial: the other patches are 1? inch and 1 inch in 
length, and present the same character. The glandular patch (so 
called) near to the cecum consists of about twenty-one crypts, of a 
larger size and deeper than those in the duodenum ; but none of 
them project externally when the intestine is distended with air. 
These occupy a space of about 2 square inches ; but in Dr. Cobbold’s 
specimen from a Giraffe as shown in the drawing (article “ Rumi- 
nantia,’’ Todd’s Cyclopzedia, and in the New Philosophical Journal 
of Edinburgh, 1856), the surface of the patch is about 5 square 
inches, and the crypts of a much larger size. So I infer that in the 
old animal they will be found of larger dimensions; but this future 
investigation must determine. 
The rectum of this animal presents a very remarkable appearance. 
The lower part of the gut, to the extent of about 8 inches, is in large, 
elevated, irregular-shaped quadrangular folds ; above these, to the 
extent of 18 inches, the lining membrane is folded longitudinally in 
a regular manner, the elevations amounting to about fifteen in num- 
ber. I have examined the intestines of a great many ruminants 
during the last eighteen months since my attention was first directed 
to this matter, and I have not seen any similar appearance. As re- 
gards the agminated patch near to the cecum, I have recently met 
with one in the same situation in the Nylghau (Antilope picta), that 
covers a much larger surface, as seen in the drawing. This patch of 
agminated crypts occupies a surface of about 4 square inches ; the 
crypts are small, and number from three to four hundred. This was 
seen in the old male Nylghau that recently broke its neck at the 
Gardens when butting at the fence. The intestinal tube of this 
Antelope measured 140 feet 9 inches; that of an old female that I 
examined some years since, 148 feet 18 inches. In the male the 
valves in the left renal vein (as shown in the drawing) amounted to 
ten, a larger number than I have yet seen. 
In conclusion I may state that I purpose placing the histology of 
these glands in the Giraffe and Nylghau before the Society on a future 
occasion. In the Eland, as I stated in my paper on the anatomy of
