 rots, sparrows. Divisions: slight and severe ; Jacksonian (partial) ; sympto- 

 matic ; idiopathic. Lesions ; inconstant ; of brain, cranium, cerebral circu- 

 lation, myelon, poisons in blood, dentition, cortical and ganglionic lesions, 

 cerebral asymmetry, stenosis of vertebral canal. Medullar asymmetry, 

 traumas of cranium, anaemia, bleeding, carotid ligation, spinal reflexes,

 jaws, fall, trembling, rigidity, involuntary discharges. Dog : trembles, 

 cries, falls, rigidity, clonic contractions, stertor, sequelae. Diagnosis: 

 sudden attack, unconsciousness, spasms, quick recovery, no spasms in 

 syncope, vertigo has no spasms, thrombosis has symptoms developed by ex- 

 ercise. Jurisprudence : animal returnable after twenty-eight days ( Wurten- 

 berg, etc.), thirty days (Prance). Treatment : of susceptible brain, and 

 peripheral irritant. Correct all irritation or disease, or expel parasites. 

 Nerve sedations : bromides, opium, valerian, belladonna, hyoscine, duboi- 

 sine. Tonics : zinc, arsenic, silver, baths, electricity. Borax. Vegetable 

 diet. Castration. Avoidance of excitement. Surgical operations. Tre- 

 phining. Excision of cortex. Outdoor life. During a Jit : amyle nitrite, 

 chloroform, ether, chloral, warm bath, cold or warmth to head, quiet se- 

 cluded place. 



Epilepsy is the name given to a class of cases characterized by 

 a sudden and transient loss of consciousness with a convulsive 

 seizure, partial or general. It appears to be due to a sudden ex- 

 plosive discharge of convulsive nervous energy, which may be 

 generated by a great number of causes of morbid irritation — 

 pathological, traumatic, or toxic. As a rule the epileptic seizure 

 is but the symptomatic expression of a complex derangement 

 which may be extremely varied as to its nature and origin. 



Frequency in different animals. The afEection is far less fre- 

 quent in the domestic animals than in man, doubtless because of
