on these points th§ presence of a case of yellow fever could be an- 

 nounced without any fea^ of alarm or panic and the measures to, 

 prevent i^s propagation put in force at once without clamor or delay. 

 The physician could act simply on the merits of the case from a pro- 

 fessional standpoint. If the disease under observation presented the 

 symptoms of yellow fever, he would announce it as su.ch without 

 st 9PP m g to consider or, for the time being, trying to determine from 

 whence, it came or obscure his judgment with considerations as to the 

 e ^ec?t o£ his diagnosis on the business interests of the locality or on 

 his, own personal interests. Such a^ condition of affairs is much to be 

 desired; ajQ,d with patience and preserverance may be attained,. 



The education of the public on this subject acts not only in this 

 indirect manner, but erectly as well, for it will so guide public 

 opinion that it will be possible to practically eliminate the transmit- 

 ting factor of the disease, the mosquito, the, stegomyia. calopus. And 

 as it is impracticable to select only the stegomyia cajopus for destruc- 

 tion, a campaign against thiSj mosquito must be a general one, and also 

 include those responsible for the transmission of malaria, filaijia, etc., 

 thu£ removing from the Tropics and subtropics some of the mpst 

 important causes of morbidity and mortality, and which heretofore, 

 have, been serious obstacles to their political, commercial, and indus- 

 trial progress. Education on this subject, therefore, I consider, of 

 prune, importance in the prophylaxis of yellow f fev§r, and i^ is sur- 

 prising h;Ow little has been done or is being done on this line. 



The, writer in his report to the surgeon-general on the yellow fever 

 epi<^emjc at Laredo, Tex., in 1903, said : 



" Insistent and continued efforts, should be made through the public 

 press and other available means to educate the people within the 

 sphere of influence of the stegomyia fasciata (calopus) , so that they 

 will learn to protect themselves againgt the invasion or spread of 

 yellow fever among them by destroying the means for the propaga- 

 tion of said mosquito and by protecting themselves against the mos- 

 quito by efficient screening. Above all, to eradicate the existing, fear, 

 in the medical profession as well as among the laity, of declaring 

 the presence of yellow fever. If the first case presenting the slightest 

 suspicious symptoms of that disease were promptly made public and 

 the proper modern precautions taken, there would be no danger of 

 the disease spreading. In fact, the public should be taught to ac- 

 knowledge the existence of yellow fever in their midst with the same 

 equanimity as they do in the case of measles or scarlatina." 



And again, in the, report of the epidemic in Vicksburg, Miss., in 

 1905, the writer stated : . . « 



" There is still much ignorance and skepticism (on the subject of 

 the method of transmission of yellow fever). An effort should be
