While attending North Central College. the author lllBrried a fellow student, the former Miss Barbara Joye Hoed •• In September, 1964, he began his graduate studies in the Department of' Anatomy, Loyola University Strltch School of Medicine, Chicago. llllnois. ii The author wishes to express his sincere appreoiation to his adviaor. Dr. Lincoln V. DOllDll, Protessor ot Anatomy, and Chairman, Department ot Anatomy, Emeritus, tor his approval of the probl•• 1nTalwable help, guidance and encouragement throughout thia investigation. The author would also like to expre.s hi. appreciation to Dr. Lealie A. Ehmert, Asslatant Prote.sor ot Anatany. tor h1a helpful critlciam and sug gestions on histochemical problema, to Dr. Robert C. Clawon. A.sistant Pro feasor ot Anatomy tor his advice and counael on avian embryology; and to Dr. Lucia Smelte, Senior Technician in the Department of Anatomy tor her help and counce! in preparing the histological material. Last, but not least, I would like to take th1a opportunity to expre.s my profound gratitude to my w1!e, Barbara. tor the aid. understanding and encouragement so generously provided.
