ner der Bauchaponeurose."* The recti muscles were well developed, 

 but the pectorales poorly. 



The muscle has been believed to be one of inspiration, where 

 function able. In this case, their large size certainly indicated 

 function, and I cannot resist the belief that that function was not 

 one of inspiration and that the deformity of the chest had been due 

 to their action. 



As was to be expected, there were numerous anomalies in other 

 parts of the body. The circulation of the upper extremities showed 

 abnormalities throughout, so much so that it was difficult to homol- 

 ogize the arterial branches in axilla, arm and hand. Circumstances 

 did not permit the careful search for variations, but two striking 

 ones may be noticed. The tendon of the digastric muscles gave off 

 two anterior bellies, one normal in size and position, the other a 

 flattened, triangular belly, meeting its fellow in a median raphe, 

 and connected at its upper angle with the maxillary symphysis. 

 Another subject, dissected at the same time, had a very similar 

 anomaly, consisting of two fleshy bellies arising from the maxilla 

 and passing down half way to the hyoid bone, there uniting in a 

 short raphe, then diverging to be inserted by a tendon into the 

 tendon of the digastric ; in both subjects the genio-hyoid was nor- 

 mal. Another anomaly in the first-mentioned subject consisted 

 of a double insertion, by two equal tendons, of the extensor indicis, 

 into the index and middle finger. 



An examination of this subject's lungs showed that death had 

 resulted from phthisis. This is the fourth subject in wluch I have 

 noticed numerous muscular and arterial anomalies coincident with 

 tuberculosis, and which incline me to the belief that persons 

 possessing such are more predisposed to this disease than those of 

 more normal structure ; or, in other words, that numerous anomalies 

 show impaired development and, lessened vitality.
