• Lying in a state of stupor; easily roused, but quickly relapsing (second day).
• Soreness of the tongue (first night).
• At 5, the next morning, diarrhœa commenced, accompanied with pain; at first diarrhœa was profuse and exhausting, with tenesmus; afterwards involuntary evacuations of mucus, slightly tinged with blood; the irritation of the bowels subsided by the following morning.
• Pulse 120 and feeble, becoming much more rapid at intervals (second day); continued rapid (between 120 and 130) until the fifth day, when it became normal.
• Twitching of the muscles of the limbs, not of those of the face (second morning); at 12.30 violent convulsions came on, lasting for an hour, and leaving the child apparently moribund, but he gradually improved, and at 3 P.M. could be roused, took some wine, and went to sleep for some hours, having convulsive movements like those of tetanus (second day); the twitchings subsided by the morning of the third day.
