 will be available to the members of the Section 

 to any extent desired.

July 2 and 3, ' meeting with the American

BIOLOGICAL SOCIETY OF WASHINGTON. 



The 357th meeting, the last of the season, 

 was held on Saturday evening, May 31. 



D. E. Salmon and C. W. Stiles presented 

 a communication, made by Dr. Stiles, on 

 'Surra, a Disease in the Philippines of Great 

 Military Importance.' The speaker stated 

 that the disease known as surra has been 

 diagnosed among the horses in the Philippines, 

 and has led to the prohibition of landing any 

 animals from those islands at any ports of 

 the United States or of the dependencies there- 

 of. 



This disease is caused by a microscopic par- 

 asite {Trypanosoma Evansi) which lives in 

 the blood, and the evidence now accessible 

 indicates that this organism is transmitted by 

 means of biting flies, especially by members 

 of the genus Tdbanus (horse-flies) ; other 

 methods of dissemination are not excluded. It 

 is chiefly a wet-weather disease, and is re- 

 ported as invariably fatal to horses and 

 mules. It occurs in other animals — such as 

 camels, elephants, dogs, cats, etc. — more rarely 

 in ruminants, and may be transmitted to 

 goats, sheep and other mammals, but is not 

 yet reported for birds. It is more or less com- 

 mon in India. Its introduction into the Phil- 

 ippines is unexplained, but it has probably ex- 

 isted there for some years past. 



Parasites closely allied to this species occur 

 in Europe, Africa and South America, in 

 some cases causing disease known as tsetse-fly 

 disease, dourine, mal de eaderas, and rat try- 

 panosomiasis. . Certain authors believe that 

 some of these maladies are identical with 

 surra. 



The chief symptoms of surra are fever, of 

 an intermittent, and sometimes relapsing 

 type; urticarial eruption; petechia on the 

 mucous membranes; progressive anemia and 

 emaciation; ravenous appetite and extreme 

 thirst; more or less paralysis. 



Treatment has not been satisfactory, but 

 arsenic has been followed by good results in 

 some cases. Prevention is difficult, but should 

 consist in protecting horses from flies. Imme- 

 diate isolation of the sick animals and pro- 

 tecting them from flies will result in restrict- 

 ing the disease. In some cases it will perhaps
