I wish that hospitals could be turned into places for experiment more than they are, in the following perfectly humane direction. Suppose two different and competing treatments of a particular malady ; I have just mentioned a case in point. Let the patients suffering under it be given the option of being placed under Dr. A. or Dr. B., the respective representatives of the two methods, and the results be statistically compared. A co-operation without partisanship between many large hospitals ought to speedily settle doubts that now hang unnecessarily long under dispute.
