Infectious Paraplegia of Solipeds in Maraju. 533 



acter, in the presence of the mature trypanosomata in the blood 

 at the beginning of a paroxysm and their disappearance toward 

 the end of it, in the supervention of rapid and extreme emacia- 

 tion, debility and anaemia, in the destruction of red blood globules 

 and the passage of the coloring matter by the kidneys, in the 

 presence of paresis and cedemas, in its expending its energy 

 mainly on the soliped and in the constancy of the mortality. 

 Death occurs in two to five months in horses, and six to twelve 

 months in asses and mules. Swine and water hogs contract the 

 disease casually and it is inoculable on white and gray rats mice, 

 rabbits, dogs, goats, sheep, chickens, turkeys, ducks and mon- 

 keys, (Nyctipithecus felinus), and exceptionally on Guinea pigs. 

 The same measures of prevention would be indicated as in cases of 

 surra and douriue.
