THE PREVENTION OF MALARIA^ 



Prof. Ronald Ross, poet, mathematician, and apostle of tropical 

 sanitation, gives us in the first half of this book the fruit of 

 twenty years' research and experience with regard to the 

 causation and prevention of a disease which, on his estimate, 

 causes " between a quarter and a half the total sickness in 

 many tropical countries." The remainder of the book consists 

 of reports from those who have put Ross's principles and 

 methods into practice in every part of the globe ; their results 

 afford a brilliant testimony to the immense value to humanity 

 of the modern discoveries regarding the etiology of malaria, a 

 subject in which Ross himself led the way and broke entirely 

 new ground. 



The aims and objects of this book are essentially practical 

 and utilitarian ; it is intended to set forth concisely and in a 

 form popularly intelligible the relevant facts concerning the 

 natural history and causation of malaria, in order to show 

 clearly how the disease may best be prevented and eradicated. 

 It is, in short, a manual of instruction for medical men, sanitary 

 officers and administrators upon whom may fall the task of 

 combating malaria in some part of the globe. For this reason 

 the more purely scientific aspects of the malarial problem, such 

 as the marvellous and complicated life-history of the parasite 

 in its two hosts, vertebrate and insect, are dealt with as briefly 

 and simply as possible. 



Whilst avoiding, however, zoological technicalities in the 

 body of the book, the author suggests in an appendix a new 

 terminology for " The Phenomena of Cytogenesis," by which is 

 meant the developmental cycle of unicellular organisms such as 

 the parasite causing malaria. If, in this age of rapid advance 

 in scientific knowledge, there be any who remember the period, 

 not much more than ten years ago, when in consequence of 

 Ross's startling discoveries with regard to the transmission
