518 ON THE BRAIN, ETC., OF HIPPOPOTAMUS. 
in all respects with the beautifully mounted specimen of a new-born 
individual in the Museum of the College of Surgeons, the latter, in 
its long cylindrical bottle, agreeing with that removed from the abdo- 
men of the adult by me in position also, its axis being longitudinal, 
the pylorus being situated almost in the pelvis. I could find no con- 
firmation of the peculiar positions of the different parts described by 
Mr. J. W. Clark in his specimen.* Along the greater curvature the 
stomach measures 15 feet. The upper (or vertebrad) compartment is 
31 inches in axial length; the second or lower, 44 inches, with a 
circumference of 45 inches in its broadest part. The cylindrical third 
stomach is 9 feet 2 inches in axial length, with an average circum- 
ference of 40 inches; there are six transverse folds of its mucous 
membrane. The cesophagus is 94 inches in circumference. 
The small intestine is 147°5 feet in length, and 5 inches in circum- 
ference. The large intestine is 21°5 feet in lengthy and 9 inches round. 
No colic cecum is developed. 
The liver of the adult is quite different from that of the new-born 
animal. It is extremely simple, elongate transversely, and narrow 
from above downwards. Its extreme transverse length is 39°25 inches, 
whilst its average measurement from vertebral to ventral margin is 
16 inches, never exceeding 16°5 inches. There are no fissures, but 
from the position of the very small umbilical notch it is evident that 
the left lobe is much the more developed of the two. With this is 
associated the peculiarity of the position of the gall-bladder, which, 
_ from the normally situated portal fissure runs directly owtwards to the

right. The gall-bladder is 2 feet long, its globose fundus projecting 
free 5 inches beyond the right margin of the liver. There is no trace 
of a Spigelian lobe, whilst the caudate is represented by a prismatic 
thickening, with a minute free apex in the position of the lobe when 
more largely developed. ‘The suspensory ligament had disappeared. 
The margins of the liver are unbroken ; and its oblong shape [rounded 
at the angles] is only slightly disturbed by a slight extra development 
upwards [vertebrad] of its left extremity. 
This liver does not at all agree with that of Sus or its allies, so 
fully described by Prof. Flower in his Hunterian Lectures of 1872.*
