g6 DISEASES OF THE DOMESTIC ANIMALS 



since the bacillus is anerobic. For the same reason thorough drain- 

 age of wounds is advisable. The treatment is often useless on 

 account of the great fatality of the disease and also endangers the 

 surgeon. Free incision of the local point of infection, and disinfec- 

 tion with hydrogen dioxide and drainage with antiseptic treatment, 

 are indicated. All carcasses should be buried 6 ft. deep and 

 covered with quicklime, or burned, and the premises thoroughly 

 cleaned and disinfected (see p. 282). 

 Electric Shock and Lightning Stroke. 



The condition simulates concussion of the brain with a state 

 of general relaxation or of spasms and convulsions. The respira- 

 tion is irregular, slow and weak or arrested. 



Cold douches should be applied to the head and the body 

 rubbed with mustard. An enema of an ounce of stronger ammonia 

 water in a quart of water may be given and the same dose repeated 

 by mouth when consciousness returns. Atropine and camphor- 

 ated oil (H. 5 iv) should be given under the skin and artificial 

 respiration continued for a long time. 



Encephalitis or Meningo-cerebritis — Inflammation of the Brain. 



Under this head we will include the various forms of men- 

 ingitis which may be combined with focal or diffuse cerebritis. It 

 is impossible to clinically discriminate between the two and thera- 

 peutically it is unnecessary, i. e., whether we have a cerebral men- 

 ingitis pure and simple, or associated with a cerebritis. 



Horses, cattle, dogs, sheep, pigs and goats are susceptible. As 

 causative factors we include infection (septicemia, emboli from 

 purulent foci, glanders, anthrax, pneumonia, tuberculosis, strangles, 

 etc.), parasites (cysticercus, oestrus, coenurus, S. armatus) ; ex- 

 cessive heat, and exertion; food poisons, unripe rye and overfeed- 

 ing with legumes; traumatism; and new growths. Some of these 

 etiological factors may be prevented. The general symptoms em- 

 brace a period of maniacal excitement, often followed by stupor and 

 coma ; the pupils, at first contracted and often unequal, react slowly
