 group of skulls taken at random from the existing inhabitants of Dublin.

Eight specimens representing this bone were found. One was from a 

 young subject, one from a tall, slender female, one from a short, stoutly built 

 male ; the rest were of average size and proportions. All were more or less 

 damaged. 



With the exception of the female specimen above referred to, all were 

 stout and strong, with well-marked prominences for the attachment of the 

 deltoid. The size nd development of this eminence made the groove for the 

 nervus radialis appear more distinct than usual, as it curved round the 

 lateral border of the bone. In one ease the groove in this position was 

 limited below by a prominent rounded projection of bone. 



One specimen showed a deficiency in the floor of the coronoid fossa, whilst 

 another showed that the mode of formation of this foramen was due to 

 absorption of the bone from in front, the anterior lamella being absent, the 

 posterior remaining, and so demonstrating that the existence of the foramen 

 was not due to the pressure of the olecranon process of the ulna. 



Eadius and Ulna. 



Three fragments of the former and four of the latter were recovered. 

 One of each was long and slender. 



The remainder were chiefly remarkable for their strength and for the 

 enormously powerful muscular impressions.
