used to relieve pain. A solution of the perchloride of iron makes 

 a good local application, in proportions of one ounce of iron to a 

 pint of water. 



SCARLATINA. 



This is a febrile disease, characterized by an eruption on the 

 skin. Spots are seen on the nose and throat. Suppuration occurs 

 in various parts of the body, and especially in connection with 

 the under jaw. The disease much resembles purpura. The sore- 

 ness of the throat, which is always present in scarlatina, gives it a 

 distinction from purpura. This sore throat is accompanied with a 

 cough, which will recede with the eruptions on the fourth or 

 fifth day. 



Tkeatmext. — Treatment is similar to purpura, with the ex- 

 ception that poultices and warm fomentations are to be used to 

 the throat. A liniment composed of equal parts of ammonia, 

 turpentine, and linseed oil may be applied to the throat in the 

 place of poultices. During convalescence the animal should be 

 exercised lightly and given good, nutritious food. 



EPIZOOTIC CEREBRO-SPINAL MENINGITIS. 



Definition. — An inflammation of the brain, spinal cord, and 

 their coverings. It is a non-contagious epizootic disease of the 

 Zymotic class, and has been confined principally to the United 

 States. In the year 1871 it played great havoc in Xew York, 

 Philadelphia, and Boston. It occurs annually in an epizootic 

 form on the sea coast of Virginia, comprising the counties of 

 Nansemond, Princess Anne, and Northampton, and the adjacent 

 counties of I^orth Carolina. Isolated cases occur throughout the 

 United States. I have witnessed it in the valleys and in the 

 mountains of. Virginia, West Virginia, Tennessee, and Maryland, 

 but never in the epizootic form. The most favorable location for 

 the development of this disease, and the one in which it has been 

 most destructive, is on Xansemond river, one of the most fertile 

 sections of Virginia east of the Blue Kidge Mountains. Here
