Microbic Diseases Individually Considered. 311 



author first, and later MM. ISTocard and Roux, showed 

 the efHcacy of this method in the protection of 

 ruminants recently bitten by rabid dogs. An emul- 

 sion is made with virulent cord in sterilized water, 

 strained through a linen cloth and injected into the 

 jugular or ear vein. The injection, w^hich should be 

 of large amount, is not attended with danger. 



Typhoid fever of the horse.^ 



Under the title of the typhoid affections several 

 diseases w^ere formally included which, clinically, had 

 not been sufficiently difiereutiated. Our knowledge 

 of these diseases is now somewhat more extended 

 through the labors of Schlitz, Perroncito, Chante- 

 messe and Delamotte, Cadeac, Galtier and Violet, 

 etc. Many points are yet to be elucidated, but two 

 diseases at least have been described which should 

 not be included in the group of typhoid affections. 

 These are pneumonia or contagious pleuro-pneu- 

 monia, and pneumo-enteritis of fodders which will 

 be considered later. 



Equine typhoid fever is especially characterized by 

 stupor and great depression of the nervous and mus- 

 cular systems of the affected animals; they are weak 

 and unsteady on their feet, hold the head low, and 

 move with a staggering gait as if under the influence 

 of a profound intoxication or narcosis ; the eyes are 

 weeping, half-closed, and often inflamed; the con- 

 junctival mucous membrane is infiltrated, blood-shot, 



* [The term •' typhoid fever," or "typhoid affections" of the 

 horse appears to include the same diseases or complications of 

 one disease which in England and America are described as In- 

 fluenza, Epizootic cellulitis, etc. — D.]
