Prevalence in Manila. The following statistics were obtained 

 through the kindness of Maj. E. C. Carter, Commissioner of Public 

 Health, from the report of Dr. John G-. Slee, chief of the veteri- 

 nary division of the Board of Health for the Philippine Islands : 



During the year between September 1, 1903, and August 31, 

 1904, 3,764 horses were imported into Manila. Of these 165 were 

 condemned and cremated for glanders and 42 condemed and cre- 

 mated for surra. All suspicious cases were tested with mallein. 



Again, through the kindness of Dr. John Ernst, veterinarian, 

 Quartermaster's Department, United States Army, it is possible to 

 state the number of public animals that died of or were destroyed 

 for glanders and surra in the Philippine Division during the fiscal 

 year ending June 30, 1904, as follows: 



It would be a mistake to assume from these statistics that glan- 

 ders was more prevalent than surra during the past year, however 

 that may be. The first series deals with imported horses only, and 

 the second series only seems to indicate the greater ease with which 

 surra can be controlled when truly military quarantine regulations 

 are put into operation. 



Susceptibility of animals. Among the Equidce, asses are most 

 susceptible to the disease, mules almost as much so, while horses 

 are slightly more resistant. Man seems to be almost as susceptible 

 as the horse. Natural infection occurs only among the Equidce 

 and in man. The disease may be transmitted by means of inocula- 

 tion to quite a number of other animals goats, sheep, young dogs, 

 cats, guinea pigs, rabbits, and field mice. A number of instances of 

 the infection of wild animals in menageries have been reported,, 

 especially among the carnivora fed on the meat of glandered horses. 

 Swine and pigeons are very slightly susceptible. Cattle, white 

 mice, rats, and domestic fowls seem to be immune. 



Modes of infection. The specific cause of the disease has never
