ilium or ischium, of the poll or the base of the brain ; also of the 

 incisor teeth. 



These paroxysms may i)e so frequent that they seem to be sub- 

 ject to remissions only, and not separated by complete intermis- 

 sions. During the paroxysms lireathing and pulsations are both 

 greatly accelerated. 



The gravity of the attack may be judged in part b}^ the vio- 

 lence and frequency of the paroxysms. Yet some cases, marked 

 by profound coma from the first, prove the most rapidl}^ fatal, 

 and the paroxysms of excitement and violence are not incompat- 

 ible with recovery. Improvement may usually be recognized by 

 the increased length of the intervals between the paroxysms, and, 

 by the shortening and moderation of the periods of excitement. 

 After the paroxysms have ceased the drowsiness or stupor gradu- 

 ally disappears, and the hyperthermia subsides. 



Even after recovery from the acute or violent symptoms there 

 is liable to remain some aberration or perversion of function, due 

 to the persistence of some encephalic or meningeal lesion. The 

 general hebetude known as immobility may bespeak dropsy of 

 the ventricles, pressure of a tumor or clot, or degeneration of 

 ganglionic centres. Diseases of the eyes (amaurosis, glaucoma, 

 cataract), or of the ear (deafness, disease of the internal or 

 middle ear) are less frequent results. 



The supervention of general or facial paraly.sis or of hemi- 

 plegia during the active progress of the malady, is an extremely 

 unfavorable symptom. 



Duration. A fatal result may take place at any time by self 

 inflicted injuries (dashing the head against a wall, or falling 

 backward and striking the head on a solid body). Apart from 

 this, death may come within twenty-four or thirty-six hours. If 

 the animal survives two to seven days recovery is more probable. 

 Hering records a case of recovery after five v/eeks illness. Hot 

 weather hastens a fatal result, while cool, cloudy weather is 

 favorable. 



Prognosis. Under rational treatment about one-fourth recover. 

 One-half of the victims make a partial recovery but remain in a 

 condition of dementia or hebetude, blindness, deafness, local or 

 general paraly.sis which renders them more or less useless. Not 

 more than one-fifth or at mo.st one-fourth of all cases recover.
