180 THEORY AND PRACTICE 



original disease than purpura. In scarlatina the hemorrhage is 

 in the form of petechise and the blood spots are scarlet, while in 

 purpura they are purple. In scarlatina there is always some sore 

 throat, in purpura never. The swellings in scarlatina are usually 

 in patches and lumps usually on the trunk, while in purpura the 

 legs swell and also the abdomen. The swellings are smooth while 

 in scarlatina they are lumpy. In scarlatina the lymphatic glands 

 suppurate, while in purpura they never do. In both diseases the 

 fever and pulse are about the same. Animals usually recover 

 from scarlatina while in purpura many die. 



Treatment. — A case of scarlatina is apt to hang on for two 

 or three weeks without any change, while a case of purpura gets 

 better or worse within a week. In scarlatina we have to treat 

 the sore throat. Put counter-irritants and bandages on the throat 

 and use such antiseptics as guaiacol. Give quinine in larger 

 doses than for purpura. Give iron gargle for the throat and 

 keep the horse mildly stimulated with nitrous ether. In some 

 bad cases the throat ulcerates and then it is a good plan to swab 

 the throat with nitrate of silver. Use the swab on the end of a 

 long stick. 



Scarlatina in the horse seems to conform with scarlet fever 

 in the human but purpura has no similarity whatever. So far as 

 the relationship between scarlatina and purpura is concerned 

 it is found that scarlatina runs into purpura before death, but 

 this does not necessarily mean that the two diseases are the same. 

 It is seldovm that animals die from scarlatina. 



Post Mortem. — In scarlatina there is an absence of the gen- 

 eral infiltration that is seen in purpura. There is difference 

 enough to warrant us in saying that the two diseases are not the 

 same. 



INFECTIOUS ANEMIA. 



This disease, known also by other names, such as Pernicious 

 Anemia, Swamp Fever, Mountain Fever, American Surra, Ma-
