NOTES ON A NEW DISEASE OF HORSES. 
By John G. Sree, D. V. S., Assistant Veterinarian, Board oe 
Hearth, Manira, P. I. 
During the past season a disease of a febrile type has been 
noted by the veterinarians affecting the foreign and native, 
horses. 
The history was at first very obscure, the disease usually 
being far advanced when first seen, the death rate large, and 
treatment unsatisfactory. 
The resident veterinarians and horse owners had noted the 
same conditions in former years, which they described as 
“ Calentura,” or fever, but did not think it had been so widely 
spread or the mortality so large as during the present season. 
Dr. H. H. Muecke, veterinarian of the Land Transportation 
Corral, says he had not noted it during the past two seasons, 
but was able to give much information concerning the disease, 
as it appeared this season in the government horses. 
That the disease was widespread was evident by the reports 
to the Board of Health, which upon investigation showed it to 
be generally present in the Island of Luzon, and in one place 
all the native horses had died, while of the government stock 
about one-half were affected. 
The first cases in native horses came under notice about the 
first part of June and presented swellings of the sheath, legs, 
and pads under the belly, in many respects similar to those of 
purpura, the membranes colorless, haemorrhagic spots on the 
membrana nictitans, but no petechial spots on the Schneiderian 
membrane, as in purpura; these were not seen in the foreign 
horses. There was always a temperature, very irregular—from 
normal at times to 105. In the native horse the disease would 
not run a very long course, anorexia appearing in the final 
stages, followed by death. 
When the horses in the corrals became affected, the symp¬ 
toms could be more easily noted, this being simply due to the 
fact that the native never notices that an animal is sick until it
