VIU PREFACE. 



ness. We also acknowledge with pleasure the valuable assistance 

 afforded us, in the departments of Materia Medica and Chemistry, 

 by Dr. Reese, Lecturer in the Medical Institute of Philadelphia. 



In preparing this compendium, the ordinary form of question 

 and answer has been avoided, as incompatible with the character 

 designed for the volume, and as occupying, with meagre questions, 

 space that might be more advantageously employed. It is hoped 

 that the arrangement adopted will be found at once concise and 

 intelligible, while we feel assured that the mechanical execution of 

 the work, its copious illustration, and neat, cheap, and convenient 

 form will prove all that can be desired by the student and prac- 

 titioner. 



Philadelphia, August 1848.
