3IO Veterinary Medicine. 



spontaneous defecation and micturition may be resumed, and the 

 patient may get on its limbs and commence feeding. There is 

 usually at first a little weakness of the limbs, but this is "transient 

 and health is restored in a very short time. The suddenness of 

 the improvement is often as marked as of the attack. The 

 patient is left prostrate and insensible, without giving any re- 

 sponse when the eyeball is touched and in two or three hours it 

 is found on its feet, eating, with eyes bright and clear. 



Some patients, however, are restored to ordinary sensation, in- 

 telligence and appetite, while the hind limbs remain paralytic, or 

 paretic, and the station and gait both weak and uncertain for 

 days or even weeks. In such cases there have been presumably 

 structural changes in the nerve centres, which require time for 

 repair. 



In fatal cases, death may occur quietly from apoplexy, cerebral 

 compression, or narcotism, or it may be preceded by a period of 

 marked excitement or disorderly muscular movements. Lifting 

 of the head, throwing it alternately on the shoulder and on the 

 ground, trembling of head, members and body, cramps or jerk- 

 ing of the limbs or of other parts, drawing the hind limbs up 

 against the abdomen, and again extending them, rolling of the 

 eyes, loud, noisy, irregular, embarrassed breathing and a run- 

 ning down pulse are often marked features. 



The temperature range is peculiar. At the start there may be 

 some hyperthermia 103° or 104°; with the advance of the dis- 

 ease it tends to become lower, 98°, 96°, or 94°. When improve- 

 ment sets in, it rises again promptly to the normal. 



Cadeac describes a special form which is ushered in by great 

 restlessness, bellowing, throwing the head to right and left, 

 grinding the teeth, sucking the tongue, salivation, licking of cer- 

 tain parts of the body, spasms in the neck, back or limbs, and 

 prompt recovery, or lapse into the comatose condition as above 

 described. It proved less fatal than the ordinary comatose type, 

 but seems to depend on similar conditions. 



Prognosis. Mortality. The disease is very deadly, the mor- 

 tality in time past having reached 40, 50 or even 60 per cent., 

 the gravity increasing as the disease set in nearer to parturition. 

 Cases occurring on the first or second day were mostly fatal, 

 those'at the end of the first week were hopeful, and those occur-
