Show 1866.] DR. E. CRISP ON THE ANATOMY OF THE GIRAFFE. 563 5. Further Observations relating to the Anatomy of the Giraffe. By E D W A R D S CRISP, M.D., F.Z.S., &c. It will be remembered that at two meetings of this Society I have described some points connected with the anatomy of the Giraffe (P. Z. S. 1864, p. 63 and p. 269). In m y first paper I gave the length of the intestinal canal of three Giraffes, in which I had measured it, and also the length of the alimentary tube of many other ruminants that I had examined, by way of contrast. In the old female Giraffe (eighteen years of age) this canal measured 254 feet, in the young male 209 feet, and in a young male aged two months 107 feet 11 inches. I mentioned in that paper that in the length of the alimentary tube the animals examined by m e differed materially from those inspected by Professor Owen, the length of the tube in the three adult animals dissected by him being only 124, 133, and 136 feet ('Transactions,' ii. p. 227). I also in that paper alluded to the account of an examination of a young Giraffe by M M . Joly and Lavocat, as described in the ' Memoires du Museum d'Histoire Naturelle de Strasbourg.' These gentlemen were astonished at the great length of the intestinal tube, which they describe as really extraordinary: it measured 65 metres 25 millimetres, or about 211 feet; but it must be remembered that this was a young animal. M M . Joly and Lavocat express their belief that the Giraffe, with the exception of the Sheep, has relatively a longer intestinal tube than any other mammal: but this is a mistake ; many mammals, including several ruminants, have, taking the length of the body into account, a longer intestinal canal than the Giraffe : the Pig, Seal, and Porpoise need only be mentioned as examples ; I could adduce many others. In m y second paper I described other points relating to the anatomy of the Giraffe, especially that in connexion with the intestinal glands (so called), and also a peculiar ridged appearance of the rectum, of which I showed wax casts, and which I thought at that time was a natural appearance. These descriptions were taken from a fourth specimen I examined, that died in the Society's Collection, probably from spasm of the glottis. In this animal, a young male aged seven months, the alimentary canal measured 123 feet 6 inches. The Society will pardon me for this repetition ; but it is necessary for the proper understanding of the subject. The recent death of a female Giraffe (the daughter of the one first inspected), aged twelve years, at the Zoological Gardens from fire has enabled me to obtain further information upon two points which I was anxious to investigate,-1st, the length of the alimentary tube; 2ndly, the appearance and size of the so-called caecal gland in an adult animal. I first ascertained by examination of the rectum that there were no such ridges or elevations as I saw and described in the young Giraffes ; so I infer that these ridges are peculiar to the young •animal, or that their presence was accidental. I have since seen in several oxen that I have examined that were killed for cattle-plague |
