224 SupracondvloicT Foramen and Processes in Man 



which he considers an accessory head of the muscle, ran into the 

 brachialis. The pronator teres, the vessels and the median nerve showed 

 no peculiarity. According to him, " Such abnormal processes with 

 abnormal prolongations of the muscles attached to them may spring, as 

 is well known, from various parts of the diaphysis above the inner con- 

 dyle." Solger considers this and two or three others, which he thinks 

 he has found in literature, as intermediate between the internal supra- 

 condyloid process and the rare external one. The cases he refers to are 

 two out of five reported by Gruber (9), and one out of four reported by 

 Turner (10). Having consulted the original papers, I am far from con- 

 vinced. Gruber himself says that his five new cases presented the same or 

 similar features as the preceding forty-two. Turner states distinctly 

 that in all four cases the process arose from the inner part of the shaft, 

 and that in all the median nerve passed under it. Perhaps the most 

 important peculiarity of. one of his cases, presumably the • one referred 

 to, is that no fibres of the pronator came from the process nor from the 

 band. The situation of the process in Solger's own case is certainly 

 very remarkable, but I cannot see that the cases he cites belong with it. 

 On the other hand, Bertaux (11) in the same year reported three cases 

 which seem to support Solger's views. Unfortunately there is no account 

 of the soft parts. Two of the specimens are from the same skeleton. The 

 right process is flattened and triangular, with a long base, continuous 

 above with the-anterior border of the bone," and prolonged below to the 

 inner border of the eoronoid fossa. The upper and lower borders of 

 the process are so symmetrical that it points neither upward nor down- 

 ward, but is turned inward so as to form something of a gutter. The 

 left one is similarly placed but is larger and with less symmetrical bor- 

 ders, the upper one being more nearly horizontal and also rougher. The 

 third instance is unilateral, on the left arm of a man of 27. The 

 process has the usual appearance, extending hook-like downwards and 

 inwards, the only important peculiarity being that it seems to be con- 

 tinuous with the anterior border. Peculiar processes, not easy to inter- 

 pret, certainly arise in this region. 



The following instance is, perhaps, worth reporting, though unfor- 

 tunately I have no data beyond those offered by the macerated humerus 

 recently added to the Warren Museum. The specimen (Fig. 2) came 

 from a white man aged 50, who evidently was of very powerful frame. 

 The humerus is strong, and the muscular ridges well developed. The
