96 PRACTICE OF EQUINE MEDICINE. 



Large doses of bismuth (2 to 4 drams) every two or three 

 hours are useful, being an internal antiseptic. 



Very small doses of bichloride of mercury; other drugs indi- 

 cated are ipecacuanha, chalk, tannic acid, copper, alum, zinc sul- 

 phate, lead acetate. 



Locally, moist heat to the abdomen. 



Injections of water, at the temperature of the body, contain- 

 ing astringents, relieve the straining. Silver nitrate (20 to 60 

 grains to the pint), injecting 2 to 4 quarts or more. Quinine 

 (1-5000, or 1-2500, or 1-1000) may be used. Injections are not 

 without danger, so care should be used. A cocaine suppository 

 may be used before the injection, to overcome the straining. 



The diet should be light, consisting of bran mashes, oatmeal 

 gruel, etc. 



CEBEBEO-SPINAL MENINGITIS. 



Give the synonym. 



Cerebro-spinal fever. 



What is the definition? 



This is a specific infectious disease, occurring sporadically 

 and in epizootics, characterized by an inflammation of the cerebro- 

 spinal meninges, and running an irregular course. 



Give the aetiology. 



It is due to a germ. Bad hygienic conditions, as damp, dark,, 

 ill-ventilated stables, excessive heat, overwork, mould from grain, 

 hay, etc., probably assist in its development. Micrococci and 

 various bacilli have been found. Prof. V. A. Moore obtained 

 cultures of a colon bacillus from the brain in one outbreak and 

 got negative results in another. 



The Diplococcus intracellularis meningitis has been isolated 

 and been constantly found present in man. 



What is the morbid anatomy? 



There may be no characteristic changes, as the majority die 

 before exudation takes place. In well-marked cases the meninges 

 of the brain and cord are inflamed, the blood-vessels standing out 

 prominently, and the ventricles contain a serous exudate.
