In favorable cases, defecation may still occur, or the rectum once emptied may fill again through the continuance of peristalsis, the milk continues to be secreted, and in one to four days, 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 response 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, intelligence 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 jerking 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 running 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 disease it tends to become lower, 98°, 96°, or 94°. When improvement 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 certain 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 mortality 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 occurring during the second week were very hopeful. With the Schmidt (iodine) treatment the mortality is claimed to be reduced to 16 or 17 per cent.
