» (1) Mr Edred M. Corner showed the following case for Dr 

 Marris. a woman, aged 28, was under the care of Dr Bastian at 

 the National Hospital, Queen's Square, for neuritis of uncertain origin. 

 On the left side of her neck an anomalous muscle was present. Its 

 origin was under the sterno-mastoid, and by means of faradisation 

 could be ascertained to be the transverse process of the atlas and 

 probably the axis also. The insertion was on the outer end of the 

 clavicle at its posterior part. Its action was to raise the clavicle. 

 The muscle was only present on the left side of the neck, and, as far 

 as was obtainable, was the only mal-development in her family

history. It was undoubtedly an example of the omo-trachelian or lev- 

 ator claviculse, so rarely seen in man, and the case, as being recognis- 

 able in the living subject, is unique. 



(2) Mr Edrbd M. Corner exhibited a Monster that had been 

 only in part examined. It was an example of a rare anencephalous and 

 acardiac condition. The birth was that of twins, the fellow of the 

 specimen shown being that of a living healthy child. Externally, 

 numerous congenital abnormalities were present, such as no anus, 

 auditory pits, etc. The blood supply to the monster had not been 

 through its umbilical cord, but through a coJinection between its scalp 

 and the placenta of the healthy foetus.
