mosquito than to overthrow this deep-seated prejudice, which begets 
apathy and indifference, characteristic of the tropical countries where 
these diseases are so prevalent. 
But now, in all parts of the world the campaign against insect car- 
riers of disease is being waged. Most instructive are the accounts— 
often from personal experience—which the author gives of the re- 
sults of this movement. For instance, the early history of yellow fever 
shows in some epidemics a mortality rate of 69 per cent. It was not 
from want of good food or water, or accommodation that men perish- 
ed. “No, they were struck down by some unseen hand, and medicine 
said that that hand was the miasm. Today we know it to be the mos- 
quito and whereas formerly, acting on the miasm theory not one life was 
ever saved, today, armed with the new knowledge, we visit the mias- 
matic countries with the same feeling of security that we do when we 
pev a visit to the continent.” 
A valuable feature is the discussion of plans of campaign against the 
guilty mosquito. Especially interesting to the American reader is the 
detailed account of the fight against yellow fever in New Orleans, in 
1905, in which Dr. Boyce, as volunteer, played an important part. The 
book is not limited, as its title would imply, to a consideration of the 
mosquito in the transmission of disease but considers also, though 
-riefly, the part played by other insects—the tsetse-fly, the rat flea, 
ticks, and the housefly. The hookworm, too, is briefly included in the 
discussion. 
Altogether, the volume is a fascinating one and should be read by 
every one who wishes to keep in touch with the advances of preven- 
tative medicine. He will put it down with the conviction that the author 
is justified in his claim that the tropical world, long retarded in its 
development by its reputation as “the white man’s grave,” is today be- 
ing steadily and surely conquered. “The three great insect-carried 
scourges of the tropics—the greatest enemies that mankind has ever 
had to contend with, namely malaria, yellow fever and sleeping sick- 
ness—are now fully in hand and giving way, and with their conquest 
disappears the awful and grinding depression which seems to have 
gripped our forefathers. * * * The tropical world is unfolding once 
again to the pioneers of commerce who now do not dread the unseen 
hand of death as did-of old the Spanish Conquistadores of Columbus 
and Cortes.”—Wwmn. A. Rirry, Cornell University.
