January 22d, 1815.--A Newfoundland dog belonging to a gentleman in Piccadilly was supposed to have swallowed a penny-piece on the 20th. On the evening of that day he was dull, refused his food, and would not follow his master. 21st. He became restless and pouting, and continually shifting his position. He would not eat nor would he drink water, but followed his mistress into her bed-room, which he had never done before, and eagerly lapped the urine from her chamber-pot. He was afterwards seen lapping his own urine. His restlessness and panting increased, He would neither eat nor drink, and made two or three attempts to vomit. 22d. He was brought to me this evening. His eyes were wild, the conjunctiva considerably inflamed, and he panted quickly and violently. There was a considerable flow of saliva from the corners of his mouth. He was extremely restless and did not remain in one position half a minute. There was an occasional convulsive nodding motion of the head. The eyes were wandering, and evidently following some imaginary object; but he was quickly recalled from his delirium by my voice or that of his master. In a few moments, however, he was wandering again. He had previously been under my care, and immediately recognised me and offered me his paw. His bark was changed and had a slight mixture of the howl, and there was a husky choking noise in the throat. I immediately declared that he was rabid, and with some reluctance on the part of his master, he was left with me. 23d, 8 A. M. The breathing was less quick and laborious. The spasm of the head was no longer visible. The flow of saliva had stopped and there was less delirium. The jaw began to be dependent: the rattling, choking noise in his throat louder. He carried straw about in his mouth. He picked up some pieces of old leather that lay within his reach and carefully concealed them under his bed. Two minutes afterwards he would take them out again, and look at them, and once more hide them. He frequently voided his urine in small quantities, but no longer lapped it. A little dog was lowered into the den, but he took no notice of it. 10 P. M. Every symptom of fever returned with increased violence. He panted very much, and did not remain in the same posture two seconds. He was continually running to the end of his chain and attempting to bite. He was eagerly and wildly watching some imaginary object. His voice was hoarser--more of the howl mixing with it. The lips were distorted, and the tongue very black. He was evidently getting weaker. After two or three attempts to escape, he would sit down for a second, and then rise and plunge to the end of his chain. He drank frequently, yet but little at a time, and that without difficulty or spasm.
