AMERICAN PUBLISHERS' ADVERTISEMENT. 



THE present volume has been printed simultaneously with the Second 

 London Edition. The numerous alterations which Dr. Carpenter has 

 introduced, and the thorough manner in which he has revised every 

 portion of it, have rendered unnecessary any notes or additions. The 

 efforts of the publishers have, therefore, been directed towards obtaining 

 a correct reprint, to accomplish which, its passage through the press 

 has been supervised by Dr. F. Gr. -Smith, Lecturer on Physiology in the 

 Philadelphia Association for Medical Instruction. It is, therefore, con- 

 fidently presented to the Profession, as in every way worthy of the 

 high reputation which it has obtained as an elementary text-book. 



PHILADELPHIA, October, 1851.
