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

 incisor teeth. 



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

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

 sions. During the paroxysms breathing and pulsations are both 

 greatly accelerated. 



The gravity of the attack may be judged in part by the vio- 

 lence and frequency of the pai;oxysms. Yel some cases, marked 

 by profound coma from the first, prove the most rapidly 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 

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

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

 middle ear) are less frequent results. 



The supervention of general or facial paralysis or of hemi- 

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

 unfavorable symtom. 



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

 inflicted injuries (dashing the head against the 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 weeks 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 paralysis which renders them more or less useless. Not 

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