astragalus, and which, in this case, existed as a separate bone known as a 

 secondary astragalus or os trigonum. 



It was attached to the body of the astragalus by a ligament all round its 

 edge. 



The posterior fasiculus of the external lateral ligament was attached to 

 the front part of the bone, which, however, did not assist in forming the 

 groove for the flexor longus hallucis. 



The bone was pyramidal in shape, with the base of the pyramid pointing 

 upwards, forwards, and slightly inwards. 



The surface was rough in appearance. 



Its size was about that of a small pea. 



This abnormality did not exist on the other limb.

Abnormal Acromion Process. 



The base of the acromion process ossified from the spine had a deep 

 fibrous fissure in it, in the lowermost part of which one of the secondary 

 centres had ossified close to the bone, but had not joined. The tip had 

 ossified, but not joined, and between the two secondary centres was thick 

 fibrous tissue with several small centres. 



There was also an ossific plate in the capsular ligament of the shoulder- 

 joint. 



The whole acromion process had a quadrilateral appearance, and was 

 large in proportion to the spine.

 regards origin from kidney and opening into bladder, but they ran close
