of protocol magnum plena [?] at Denver & del [?] [illegible] to judge of the effect on it, I would say that Agnew's studies & Kline's study are the most valuable as they are based on the actual cases which were studied. The other studies were not so good. One was made by a student at the University of Illinois who had an opportunity of studying some 200 cases and this study is probably the best of them. There appears to be little difference in the results obtained from the two groups but the one group was very small and the other large enough to make it impossible to draw any conclusions as to the value of the treatment. I have not been able to find any reference to the case of a child who was treated by Dr. [illegible] at Denver and who had a complete recovery after being treated for 6 months.
