fatal and infected wounds heal more slowly. This is due to 

 the lower vitalit}^ of the animal and to the hot and moist 

 climate, which favors germ growth. Pneumonia is almost 

 always fatal in the Philippines. Canker and thrush are found 

 in the most aggravated type. Periodic ophthalmia is very 

 l^revalent, resulting in many animals becoming blind. Heat- 

 stroke is a frequent occurrence, on account of the excessive 

 heat and moisture, and is fatal in the majorit}^ of cases. The 

 temperature in heatstroke frequently rises to 110° to 113° F. 

 Glanders, which is very common, runs a rapid and fatal course. 

 American horses rarely suffer from the chronic form of the 

 disease often manifested in cooler climates. 



In the tropics, a careful daily inspection of the horses should 

 be made and the temperature of every animal should be taken 

 at least once a week. Any animal with a suspicious discharge 

 from the nose or with sores upon the bod}^ indicating farcy 

 buds, and any animal showing a rise of 2 degrees above normal 

 temperature, should be isolated and kept under observation by 

 a veterinarian. In case of an outbreak, temperatures should 

 be taken daily. Normal temperature in the tropics is usually 

 about 1 degree higher than in a cool climate, and it may rise as 

 much as -1 degrees with exercise of a moderate nature. These 

 facts should be taken into consideration in recording tempera- 

 tures.
