'Rabies in the Cat'.--Fortunately for us, this does not often occur; for a mad cat is a truly ferocious animal. I have seen two cases, one of them to my cost; yet, I am unable to give any satisfactory account of the progress of the disease. The first stage seems to be one of sullenness, and which would probably last to death; but from that sullenness it is dangerous to rouse the animal. It probably would not, except in the paroxysm of rage, attack any one; but during that paroxysm it knows no fear, nor has its ferocity any bounds. A cat, that had been the inhabitant of a nursery, and the playmate of the children, had all at once become sullen and ill-tempered. It had taken refuge in an upper room, and could not be coaxed from the corner in which it had crouched. It was nearly dark when I went. I saw the horrible glare of her eyes, but I could not see so much of her as I wished, and I said that I would call again in the morning. I found the patient, on the following day, precisely in the same situation and the same attitude, crouched up in a corner, and ready to spring. I was very much interested in the case; and as I wanted to study the countenance of this demon, for she looked like one, I was foolishly, inexcusably imprudent. I went on my hands and knees, and brought my face nearly on a level with hers, and gazed on those glaring eyes, and that horrible countenance, until I seemed to feel the deathly influence of a spell stealing over me. I was not afraid, but every mental and bodily power was in a manner suspended. My countenance, perhaps, alarmed her, for she sprang on me, fastened herself on my face, and bit through both my lips. She then darted down stairs, and, I believe, was never seen again. I always have nitrate of silver in my pocket, even now I am never without it; I washed myself, and applied the caustic with some severity to the wound; and my medical adviser and valued friend, Mr. Millington, punished me still more after I got home. My object was attained, although at somewhat too much cost, for the expression of that brute's countenance will never be forgotten. The later symptoms of rabies in this animal, no one, perhaps, has had the opportunity of observing: we witness only the sullenness and the ferocity.
