BELMULLET WHALING STATION. 139 
(c) A number of greenish bodies were taken from a similar position 
in the Sperm Whale. The specimens are about 2} in. long, about 
2 in. wide, and # in. thick, at the thickest part. The histological 
condition is exceedingly bad, as was to be expected from the general 
state of all the Sperm Whales which we saw. ‘There is a connective- 
tissue capsule, and a great mass of the body is composed of the 
same tissue. There are two or three objects which may be sections 
of medullated nerves, and a number of rather thick-walled blood- 
vessels. No other structures can be recognised. 
(d) The rectum of Physeter has an exceedingly well-developed 
cuticular lining for the last four or six feet of its length. In the

first specimen in which it was observed the lining was detached owing 
to decomposition, but in a later example it was found to be attached 
to the remainder of the intestinal wall. This lining is about 4 in. 
thick. It has a pale yellow colour, and is of a consistency somewhat 
resembling that of a very hard-boiled egg. It is laminated, and can 
be readily split into layers. At irregular distances on the surface 
are hollows, penetrating partly or completely through the lining. The 
edges of these hollows have a puckered appearance. The line of 
junction of this lining with the mucosa of the intestine is perfectly 
sharp. The lining thins out very much just prior to its cessation, 
and the edges of successive lamine are readily observed. The actual 
thickness of the lining where it comes to an end is ts in. The colour 
of the mucous membrane, which is fairly tough, is a dull pink, very 
much stained with sepia. Longitudinal sections of this region at 
the point of junction clearly show that this is a cuticle derived from 
the stratified epithelium of the rectum. The cuticle comes to a 
very abrupt termination, where it joins the mucosa, the line of
