422 TWING B. WIGGINS 



United States army, consisting of Drs. Walter Reed, Carroll, 

 Lazear and Agramonte have been conclusive and convincing. 

 They show that yellow fever can only be transmitted by means 

 of an intermediate host — probably the mosquito, culex fas- 

 ciatus, which has previously fed on the blood of infected per- 

 sons. The death of Lazear from the disease during the in- 

 vestigations adds one more name to the martyrs to science. 



At this time the founding of endowed laboratories for 

 original research, together with the high requirements set by 

 the great schools of Baltimore, Philadelphia, New York and 

 Chicago, and at least one school of the same rank in each state, 

 make it possible for every diligent student to find a scientific 

 education of a high order. In several of our best schools a 

 preliminary degree in arts or sciences is a pre-requisite for ad- 

 mission. This must in time be the practice of all. 



In 1898-99 there were 151 medical schools with 23,778 

 students in attendance. There were 4,389 instructors and 4,911 

 students graduated, of whom 480 held the degree of A. B. or 

 B. S. All but fifteen of the above schools gave a graded course 

 of four years, and in some the months of required attendance 

 in one year are equal to the total required attendance of twenty 

 years ago. All this shows true progress and it is interesting 

 to note that among even the most highly trained men, only 

 about one in five becomes a specialist. The rewards which 

 come to the physician who truly understands his mission, are 

 many and various. Aside from the livelihood which affords 

 him subsistence, he has the higher reward of work well done. 

 He belongs to a brotherhood of earnest seekers after truth, 

 which embraces the whole world, and whose unselfish ambition 

 it is to prevent disease and banish human suffering.
