PREFACE. 



A life devoted almost exclusively to Medical Sci- 

 ence as a profession, affords but little time for the 

 cultivation of the necessary qualifications for a pop- 

 ular writer ; and as such the author of these pages 

 has never thought of venturing a claim. It has been 

 his desire, in writing this work, to furnish the travel- 

 ling public especially, with some needful information 

 concerning the Isthmus of Panama, and thus making 

 a useful, rather than a pleasing book.
