transmission of Yellow Fever at Vera Cruz. Lastly in 1905 the 

 Liverpool School of Tropical Medicine has established for a second 

 time a Yellow Fever Laboratory at Para under the direction of 

 Dr. Thomas, assisted by Dr. Breinl. The conclusions arrived at by 

 these Commissions, as well as by Dr. Guiteras in Havana and Drs. 

 Lutz, Ribas, Barreto, de Barros and Rodriques in Brazil, have 

 all fully confirmed the original observations of Reed, Agramonte, 

 Carroll and Lazear, and have proved that the Stegomyia fasciata is 

 the sole transmitter of the disease. The enthusiasm and devotion 

 of this army of workers is shown by the fact that a very large 

 number of the workers suffered themselves from the disease, and that 

 Walter Myers and Lazear succumbed. Reed, one of the most 

 brilliant of this group, unfortunately died at Washington from 

 appendicitis in 1902, hardly before he had had time to witness the 

 beneficial results of his remarkable labours. The flood of new light 

 which was thrown upon the nature of Yellow Fever soon began to 

 have its effect. The first great application of the new principle of 

 prevention of Yellow Fever was made at Havana in 1901 by Major 

 Gorgas, under the very able administration of General Wood. The 

 result was a complete success ; it has become historic and constitutes 

 the example to every town in the Yellow Fever zone of the truth of 

 the doctrine of the mosquito transmission and the practicability of its 

 application. The example has been followed ; under Dr. Cruz, in 

 Rio, and Dr. Liceaga, in Mexico, great improvements have been 

 brought about, but an immense amount of work still remains to be 

 done. A new stimulus has, however, now been furnished by the 

 successful campaign of 1905 in New Orleans, and it is to be hoped 

 that a great deal of the opposition and apathy still to be met with 

 will soon give place to hearty co-operation and determination to rid 

 Yellow Fever countries of a pest which causes so much suffering and 

 cripples commerce.
