Scarlatina. — A disease newl}' discovered in light-colored horses, 

 attended b\' sore throat, as in man, and with slight fever and dry 

 skin — the glands of the neck are slightly swollen, and in about 

 two days the lining membranes within the nose and lips become 

 studded with scarlet spots about the size of a garden pea, which 

 run together. In light bay horses will be seen patches from which 

 the hair falls off and is replaced by a coat of a lighter color, thus 

 making the animal look as if he had had an attack of varioloid or 

 small-pox. Scarlatina is an eruptive fever, running a fixed and 

 definite course, and is closely allied to purpura, influenza and 

 strangles (all of which see). 



Treatment. Place the horse in a cool place, and give small doses- 

 of aconite, followed b}^ gentian and carbonate of ammonia. In a 

 few days iron ma}' be added. (See Medicines.)

 swelling does not grow less after extra feed is allowed, and a few 

 iron powders are given, the scrotum will have to be opened a little 

 on both sides to allow the fluid to flow out. Do not mistake the 

 swelling for scrotal rupture. (See Ruptures.)
