A spaniel, seemingly at play, snapped, in the morning, at the feet of several persons. In the evening he bit his master, his master's friend, and another dog. The old habits of obedience and affection then returned. His master, most strangely, did not suspect the truth, and brought the animal to me to be examined. The animal was, as I had often seen him, perfectly docile and eager to be caressed. At my suggestion, or rather entreaty, he was left with me. On the following morning the disease was plain enough, and on the following day he died. A post-mortem examination took place, and proved that he was unequivocally rabid. A lady would nurse her dog, after I had declared it to be rabid, and when he was dangerous to every one but herself, and even to her from the saliva which he plentifully scattered about. At length he darted at every one that entered the room, until a footman keeping the animal at bay with the poker, the husband of the lady dragged her from the room. The noise that the dog made was then terrific, and he almost gnawed his way through the door. At midnight his violence nearly ceased, and the door was partially opened. He was staggering and falling about, with every limb violently agitated. At the entreaty of the lady, a servant ventured in to make a kind of bed for him. The dog suddenly darted at him, and dropped and died. A terrier, ten years old, had been ill, and refused all food for three days. On the fourth day he bit a cat of which he had been unusually fond, and he likewise bit three dogs. I was requested to see him. I found him loose in the kitchen, and at first refused to go in, but, after observing him for a minute or two, I thought that I might venture. He had a peculiarly wild and eager look, and turned sharply round at the least noise. He often watched the flight of some imaginary object, and pursued with the utmost fury every fly that he saw. He searchingly sniffed about the room, and examined my legs with an eagerness that made me absolutely tremble. His quarrel with the cat had been made up, and when he was not otherwise employed he was eagerly licking her and her kittens. In the excess or derangement of his fondness, he fairly rolled them from one end of the kitchen to another. With difficulty I induced his master to permit me to destroy him.
