acquired the knack — either along prac- 

 tical or scientific lines — to select his 

 cases properly. Could he be sure that a 

 given case would yield to applications 

 of iodine preparations, he would much 

 prefer to treat it that way; but he is 

 not often sure. He has learned that 

 there are certain cases, although to all 

 appearances, as far as he is able to tell, 

 not differing from other cases of the 

 same nature, will yield to actual cau- 

 tery; he has learned, also, that certain 

 cases will yield to local applications of 

 certain iodine preparations. But he 

 finds it difficult to select these cases for 

 the respective forms of treatment in 

 the general run of his practice. That he 

 may be better able to serve his clients, 

 and that he may even more highly ap- 

 preciate the therapeutic worth of iodine 

 in some of its forms of preparation, I 

 have made some clinical observations, 

 in my own practice, which I shall record
