214 MR, J. B. SUTTON ON DISEASES OF [Apr. 20, 
from its connection with the peritoneal cavity. A few fibres of the 
cremaster muscle are spread over its upper limits. Inside this, and 
in close apposition with its walls, is the tunica albuginea, greatly 
distended, with the epididymis stretched over it like a strap. On 
. cutting into it, a pint of straw-coloured fluid escaped. This liquid 
was alkaline in reaction (sp. gr. 1020), and contained one half its 
volume of albumen. 
The substance of the testicle presented a very remarkable appear- 
ance, for it looked like the roots of a tree in. miniature. There was a 
central main stem, and from it slender rounded rootlets composed of - 
testicular substance, 7. e. seminiferous tubules and connective tissue, 
passed outwards to the sac-walls. ‘The appearances were the same 
in both testes. The condition is best expressed by saying that it 
resembled a hydrocele, except that the fluid was within the tunica 
albuginea instead of in the cavity of the tunica vaginalis. 
The occiput of an Ichneumon, with dislocation of the atlas and subsequent 
; ankylosis of that-bone to the occiput. 
The specimen has been brought before the notice of the Society, 
with the hope of inducing others who have opportunities of seeing 
similar cases to place a description of them on record. 
In 1879 Prof. Flower gave an account of a very remarkable con- 
dition presented by the occiput of a Beluga. In this Whale the 
atlas had become dislocated from the occipital condyles, and dis- 
placed in such a manner that the passage for the spinal cord at the 
foramen magnum had become reduced to a very narrow chink, only 
three quarters of an inch in transverse measurement. The Whale 
had survived the accident some considerable time, for the displaced
