concentriques dont elle est formée.

qui la font paraitre articulée. De cet emboitement la superposition a 
lieu de la pointe vers la base, et non de la base vers la pointe, comme, 
par erreur, le fait croire les figs. 14 et 15 de la Pl. II. de l’ouvrage de

5. FurtTHER ConTRIBUTIONS TO THE ANATOMY OF THE GIRAFFE 
AND THE NyteHavu. By Epwarps Crisp, M.D., F.Z.S., 
ETC. 
It will be remembered that, in a paper on the visceral anatomy of 
the Giraffe and on the anatomy of the Eland (Oreas canna), lately 
read (Proc. Zool. Soc., 1864, p. 63), I stated that I had found a re- 
markable appearance in the rectum of the young Giraffe, that I had 
mislaid the parts, and that I spoke only from recollection. The death 
of the young male Giraffe at the Gardens, that occurred in April last, 
has, however, enabled me to place the rectum and intestinal glands 
of this animal before the Society. I have taken sketches and wax 
casts of all the parts, so that the appearances will readily be under- 
stood. The animal in question, aged seven months, for some time 
after birth was strong and healthy ; but of late it has showed signs 
of indisposition, and died very suddenly—its tongue, as the keeper 
informs me, “ being at the time of death curled round in its mouth,” 
so that it probably died from some cerebral lesion, as I failed to 
discover any disease in the thoracic and abdominal viscera: and it 
it satisfactory to know that in these parts there was no evidence of a 
tuberculous taint. 
The animal weighed about 3 cwt. The intestinal canal measured 
123 feet 6 inches in length, including the large intestines (33 feet) ; 
that of the one before described, which was two months old, 107 feet 
11 inches; so that we may form some notion of the rate of growth 
of this tube. The tracheal rings in this specimen amounted to one 
hundred ; but in the old Giraffe I stated that they numbered more 
than two hundred ; it is possible, however, that I may have made a 
mistake in my notes. The examination of an old animal, however, 
will clear up this doubt, as it will the interesting point in relation 
to the size of the intestinal glands. 
I need not again describe the viscera that are now so well known ; 
but I will mention a fact in relation to the heart that has not before 
been noticed. As mentioned in my former paper, the apex is more 
pointed than in any of the Antelopes. In this young specimen the 
heart weighed 1 lb. 14 ozs.; the columnee carnez were very indistinct ; 
the chordee tendineze amounted to thirteen; the parietes of the left 
ventricle, at their thickest part, measured 17 inch, those of the right 
ventricle only ? inch, the septum ventriculorum 1 inch. The length, 
from the root, of the aorta 7 inches ; greatest width 5 inches. The 
most remarkable circumstance was the absence of the heart-bone; and 
it-will be curious hereafter to trace the development of this bone in
