PREFACE TO SECOND EDITION 



THE necessity for a second edition has afforded the 

 opportunity not only of making certain slight verbal 

 changes in the text but of substituting for the modified 

 Sylvester method of resuscitation from drowning Scha- 

 fer's new prone pressure method, and of adding a table 

 of infectious diseases which gives the incubation periods, 

 early symptoms, modes of entry, causes and school 

 quarantine periods for the several diseases, including 

 common diseases of the skin and eyes.
