A dictionary must be full enough to give the student the information 

 he seeks, clearly and simply, yet it must not confuse him with detail. 

 The editor has kept this in mind in compiling this Pocket Dictionary, 

 and he has produced a work of great value to the student. There are 

 over 100,000 American Medical Dictionaries now in use. 

 I. V. S. Stanislaus, M.D., Medico-Chirurgical College: "We have 

 been strongly recommending this little book as being the very best."
