YELLOW FEVER 263 



disease and requires the same measures of protection against 

 mosquitoes. On the assumption that mosquitoes remain in the 

 vicinity of their breeding places, or never travel far, the pre- 

 valence of malarial fever at a post would indicate want of proper 

 care and diligence on the part of the surgeon and commanding 

 officer in complying with General Orders No. 6, Department of 

 Cuba, 1900. 



" 7. Surgeons are again reminded of the absolute necessity, in 

 all fever cases, to keep, from the very beginning, a complete 

 chart of pulse and temperature, since such a chart is their 

 best guide to a correct diagnosis and the proper treatment.

The practical execution, in the city of Havana, by 

 Major 1 Gorgas, Surgeon U. S. A., chief sanitary offi- 

 cer of the city during its occupation by our troops, 

 of the measures indicated in the above circular was 

 attended with entire success. For more than two 

 years this city has been entirely free from cases of 

 yellow fever, while for many years prior to the date 

 when Major Gorgas inaugurated his war upon in- 

 fected mosquitoes the disease had prevailed to a 

 greater or less extent annually and a certain number 

 of deaths had occurred every month in the year. 



1 Now Colonel Gorgas, by special act of Congress, as a reward for his 

 services.
