[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, i. e. seminiferous tubules and connective tissue, 

 passed outwards to the sac-walls. The appearances were the same 

 in botli testes. The condition is best expressed by saving that it 

 resembled a hydrocele, except that the fluid was within the tunica 

 albuginea instead of in the cavity of the tunica vaginalis.

The ouciput 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 I'educed 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
