end of the paln)ar surface. Each of the three forms a part of the 

 distal articular surface. Pfitzner had recognized the capitatum 

 secondariuni before he had seen a paper in which Gruber had de- 

 scribed an instance of its independent (separate) existence. This still 

 remains an unique observation. Pfitzner met his lamented death 

 without ever having seen a separate subcapitatum. I found it near 

 the close of last season's anatomical work in both hands of a white 

 man aged 54. It is a great regret to me that the enthusiastic in- 

 vestigator should not have lived to see this additional confirmation of 

 his theory. It is perfectly analogous to that of Schwalbe's observ- 

 ation of a separate cuboides secundarium. (I may say that there is 

 a specimen of the latter in our Museum synostosed with the scaphoid 

 which I cannot doubt at an earlier period, probably in adult life, had 

 been joined to it only by cartilage.) 



Pfitzner describes the subcapitatum as lying in the palm of the 

 hand between the trapezoid and the hamatum (unciform), synostosed 

 with the distal portion of the capitatum and articulating with the 

 3rd metacarpal. It is more on the radial than on the ulnar side, 

 usually articulating with the trapezoid, almost always with the 2nd
