PREFACE. 



The subject of Tropical Medicine, considered in its broadest 

 sense, has become vaster tlian any other specialized branch of the 

 Medical Sciences. The comprehensiveness of the subject is only 

 irealized when one undertakes a course of study at one of the Tropical 

 Schools, a course particularly essential, but all too short in order to 

 become acquainted with the various branches of the subject. The 

 student finds that he must gather together his knowledge from as 

 many imposing text-books in the three or six months of his study as 

 he required for the whole of his cjualifying examinations, a task almost 

 impossible in the lime. Also the busy tropical practitioner, who 

 requires adequate essential information, cannot consult libraries or 

 include large volumes in his limited equipment, and if he had them 

 he would find it a somewhat laborious task to peruse them for the few 

 essential facts he needed to know. 



This work contains nothing new. It is not intended to sub- 

 stitute any other work. It is a digest of our knowledge of Tropical 

 Medicine, including Skin Diseases, Eye Diseases, Venoms, Hygiene 

 and Laboratory Hints in a form handy for ready reference : the 

 vade-mecum of the student and busy tropical practitioner. 



It was commenced for the sole use of the writer, but it has been 

 suggested that its utility would be appreciated in a wider field. In 

 tlie event of another edition being- required the writer would welcome 

 any suggestions for its improvement from medical men.
