COPY December 19, 1959. Dre Fe Ce Allen, Basketball Coach, University of Kansas, Lawrence, Kansase Dear Dre Allens For some time I have been very much interested in means of pbuilding cardiac reserve. Accumulated evidence in the last few years would indicate that the giving of vitamin B compound, glycine, and dex- trose would aid in restoring cardiac reserve when it is lest through various types of disease. For several years now we have employed these methods in our practice and have been impressed with the improvement shown in many of these patients. It occurred to me that this improvement can be brought about in © exhausted hearts from disease, why wouldn't it be possible to improve cardiac reserve in those who are under great physical strain, and with your cooperation I would be very mush pleased to try it on some of your playerse I would suggest that we start with a few members so that we will have some method of control as to the value of our results. The following is the method I would like to follows One capsule of betulin compound three times daily after meals A tablespoon full of dexin (destrose sugar made by Burrows & _ . Wellcome) in glass of lemonade ten minutes before game time and between halfs. A tablespoon full of glycolixer by Squibb (glycine) three times dailye Please let me know your reaction and if you have any suggestions to adde Sincerely yours, (Signed) Don Carlos Peete, Mele
