LEADING SCHOOL OF TROPICAL MEDICINE 3 43 



not only able to say that the cause of the fever was a spirochete, but 

 was able to prove by experiment that the spirochete was conveyed to 

 the healthy subject by the bite of a tick, the Ornithodoros moubata, 

 and that the larvae hatched from eggs laid by an infected tick, could 

 convey the infection at their first feed. 



Dutton's work in the Congo, on tick fever, was interrupted by the 

 illness of both members of the expedition. This occurred at the time 

 that Ross and Milne published the results of their discovery in Uganda. 

 In February, 1905, three months later, Dutton died in Africa. 



Further experiments were carried on in the laboratories at Run- 

 corn, where it was found that the spirochete of African tick fever was 

 a new parasite, quite different from a similar organism which causes 

 the relapsing fever of Europe. By common consent this new parasite 

 was called Spirochceta duttoni, in honor of the hero who gave his life 

 in an effort to relieve suffering humanity. 



Such have been the results gained by the school in a study of five 

 parasitic diseases conveyed by mosquitoes, flies and ticks. There are 

 many other investigations of importance to the physician and scientist, 

 but of less general interest. How valuable the work of the school may 

 be in lines not strictly medical was recently demonstrated in the West 

 Indies by Mr. Newstead, the entomologist of the twenty-first expedition. 



This institution, great as it is, has been supported chiefly by annual 

 subscriptions, as the school has no endowment. Foremost among those 

 who have contributed most liberally is Sir Alfred Jones, who founded 

 it. Another benefactor, who has shown his appreciation of the work 

 done in the Congo, is the King of Belgium; and recently the English 

 government has given its support. Much of the work has been planned 

 and the interest in it aroused by the Dean, Sir Rubert Boyce. 



This school, in the short space of ten years, has accomplished more 

 than many an older institution.
