REYIEWS OF BOOKS. 



Sea-Ai'r and Sea-Bathing By John H. 

 Packard, M. D., Surgeon to the Episco- 

 pal Hospital, etc. Philadelphia : Pres- 

 ley Blakiston. 1880. (50 cents.) 



This little volume is one of a valuable 

 series of "American Health Primers " 

 which have been written " to diffuse as 

 widely and cheaply as possible, among all 

 classes, a knowledge of the elementary 

 facts of preventive medicine, and the 

 bearings and applications of the latest and 

 best researches in every branch of medi- 

 cal and hygienic science." 



We have read the book with much in- 

 terest, and have been well rewarded for 

 the time thus spent. There is no doubt 

 that, while sea-air and sea-bathing are in- 

 vigorating and stimulating to almost every 

 person, a little knowledge of how they act 

 and how their most beneficial eiifects can 

 be obtained, would be valuable to all who 

 visit the sea-shore, and would sometimes 

 prevent accidents which result from neg- 

 lect or ignorance of a few simple rules. 

 Just the information which visitors to the 

 sea-shore require, is given in this book.
