160 BOVINE PATHOLOGY. 



ordinary antiphlogistic means. Avoid communicating the 

 disease from sick to healthy animals when milking ; iso- 

 lation is seldom necessary. Eeject the milk. 



Sometimes customers bring dogs to the veterinary 

 surgeon that they may be vaccinated as a preventive 

 against distemper. We have no proof that this is of the 

 slightest value ; on the contrary, evidence is not wanting 

 to prove the fallacy of this method. 



Infectious Aphtha is described by some authors 

 as affecting cattle. Eczema epizootica is frequently 

 called aphthous fever, and a form of aphtha, of an 

 enzootic character, is sometimes seen as a result of special 

 characters of food supplied to a number of animals. 

 Probably the true '' infectious '^ form is the acuminated 

 varicella mentioned above, the mouth being involved. The 

 vesicae are numerous, conical in shape, and occur in all 

 parts of the mouth ; thus, the disease may be distinguished 

 from eczema epizootica. This aphtha is said to be most 

 frequently met with, in India and other warm countries ; 

 we are inclined to think that in the majority of cases it is 

 simply foot-and-mouth disease. Our knowledge of the 

 cattle diseases of India is scanty and indefinite. Doubt- 

 less, when scientific investigations of them have been 

 made, we shall find our list of exanthemata enlarged. 



Stomatitis Pustulosa Equi, described by Professors 

 Eggeling and Ellenberger (see ' Veterinary Journal,^ vii, 

 306), is communicable to cattle by inoculation and from 

 one cow to another. Nodules first formed ; these became 

 pustules, which burst and produced superficial ulcers; 

 these increased in size, and then commenced healing, a 

 scab being formed. The contagion may occur from the 

 skin, but takes place most readily from the mucous mem- 

 brane. The virus, when passed through several animals, 

 seems to lose its potency. 



Fleming, in his ' Veterinary Sanitary Science and 

 Police,^ mentions a bovine aphthous disease of the genital 

 organs as observed by Numan, of Utrecht, in 1831, since 

 when it has several times appeared in Holland. It is 

 anthracoid, gives rise to malignant carbuncle in man, and
