Quite recently I have beenconsulted in the case of a lad aboutfourteen years of age, who had beensubjected to the pulleys during fourconsecutive hours to accomplish amore complete reduction. The same thing, also, has beennoticed by me occasionally wherethe shoulder had been subjected toa violent wrench, but no actual dis-location had ever occurred. In eithercase the explanation is perhaps thesame, the long head of the biceps hasbeen broken or displaced ; or, when it follows a dislocation, some of themuscles inserted into the greater tuberosity have been torn from theirattachments. I mean to say that in these circumstances we may find 1 Araer. Journ. Med. ScL, vol. xvi. p. 219, May, 1835, from Lond. Med. Gaz. 2 Ibid., vol, xxix. p. 480, from Lond. Med.

I have seen one example in theperson of Mr. Craig, of Brooklyn, in which the tendon of the bicepssuddenly resumed its position after the lapse of several days, and theprominence of the head of the humerus at once disappeared. Alfred Mercer, of Syracuse, N. Y., in a very interesting paper onthis same subject, relates several examples of forward displacementafter injuries to the shoulder-joint, one of which, as being exceedinglypertinent, I shall take the liberty of quoting. Mrs. B, a well-developed woman, of full habit, aged fifty-six, sevenyears since was thrown from a carriage, dislocating her right shoulder,which was re
