DISEASES OF THE NERVOUS SYSTEM. 135 



a quart or more of water, and even then care should be exercised in 

 drenching. 



Iii cases when the shock has not caused complete insensibility recov- 

 ery may be hastened by the ammonia and water drench, or 4 ounces of 

 brandy diluted with a quart of water, or 8 ounces of whisky diluted 

 with a quart of water. These doses may be given every three or four 

 hours, if necessary. After recovery from the more serious symptoms, 

 2 drams of sulphate of quinine should be given twice a day until health 

 is restored. If any paralysis remains, 1 drams of pulverized mix 

 vomica should be given twice a day with the quinine. 



The foregoing treatment is also applicable when the electrical shock 

 is given by telephone, electric car, or electric light wires, etc. The 

 wounds, burns, or blisters should be treated according to the antiseptic 

 method of treating wounds. 



TUMOKS IN THE BRAIN, ETC. 



Tumors of different kinds have been found within the cranial cavity, 

 and in many cases there have been no well-marked symptoms exhib- 

 ited during the life of the animal to lead one to suspect their existence. 

 Cases are recorded where bony tumors have been found in the brain of 

 cattle that died suddenly, but during life no signs of disease were man- 

 ifested. Post-mortem examinations have discovered tubercular matter 

 in the membranes of the brain (see Tuberculosis, p. 403). Abscesses, 

 usually the result of inflammation of the brain, have been found post- 

 mortem. For the description of hydrocephalus, or dropsy of the brain 

 of calves, the reader is referred to the section on parturition. (See 

 Water in the Head, p. 200.) 



Chorea, constant twitching and irregular spasmodic movements of 

 the muscles, has been noticed in connection with, or as a sequel to 

 other affections, as, for example, parturient apoplexy. 



Various diseases, the description of which will be found in other sec- 

 tions of this work, affect the nervous system to a greater or less extent. 

 For example, ergotism, lead poisoning, unemia, parturient apoplexy, 

 colic, and other affections associated with cramps or spasms, etc. Dis- 

 ease of the ovaries, by reflex irritation, may cause u'stromania (see 

 Excess of Venereal Diwire, p. 170), constant desire for the bull.
