The Symptoms of Rabies Part 2

M. Magendie has often injected into the veins of an hydrophobous dog as much as five grains of opium without producing any effect; while a single grain given to the healthy dog would suffice to send him almost to sleep.
One of Mr. Babington's patients thought that there was a cloud of flies about him. "Why do you not kill those flies!" he would cry; and then he would strike at them with his hand, and shrink under the bed-clothes, in the most dreadful fear.
There is also in the human being a peculiarity in this delirium which seems to distinguish it from every other kind of mental aberration.
"The patient," in Mr. Lawrence's language, "is pursued by a thousand phantoms that intrude themselves upon his mind; he holds conversation with imaginary persons; he fancies himself surrounded with difficulties, and in the greatest distress. These thoughts seem to pass through his mind with wonderful rapidity, and to keep him in a state of the greatest distress, unless he is quickly spoken to or addressed by his name, and, then, in a moment the charm is broken; every phantom of imagination disappears, and at once he begins to talk as calmly and as connectedly as in perfect health."
So it is with the dog, whether he is watching the motes that are floating in the air, or the insects that are annoying him on the walls, or the foes that he fancies are threatening him on every side — one word recalls him in a moment. Dispersed by the magic influence of his master's voice, every object of terror disappears, and he crawls towards him with the same peculiar expression of attachment that used to characterize him.
Then comes a moment's pause — a moment of actual vacuity — the eye slowly closes, the head droops, and he seems as if his fore feet were giving way, and he would fall: but he springs up again, every object of terror once more surrounds him — he gazes wildly around — he snaps — he barks, and he rushes to the extent of his chain, prepared to meet his imaginary foe.
The expression of the countenance of the dog undergoes a considerable change, principally dependent on the previous disposition of the animal. If he was naturally of an affectionate disposition, there will be an anxious, inquiring countenance, eloquent, beyond the power of resisting its influence. It is made up of strange suppositions as to the nature of the depression of mind under which he labours, mingled with some passing doubts, and they are but passing, as to the concern which the master has in the affair; but, most of all, there is an affectionate and confiding appeal for relief. At the same time we observe some strange fancy, evidently passing through his mind, unalloyed, however, by the slightest portion of ferocity.
In the countenance of the naturally savage brute, or him that has been trained to be savage, there is indeed a fearful change; sometimes the conjunctiva is highly injected; at other times it is scarcely affected, but the eyes have an unusually bright and dazzling appearance. They are like two balls of fire, and there is a peculiar transparency of the hyaloid membrane, or injection of that of the retina.
A very early symptom of rabies in the dog, is an extreme degree of restlessness. Frequently, he is almost invariably wandering about, shifting from corner to corner, or continually rising up and lying down, changing his posture in every possible way, disposing of his bed with his paws, shaking it with his mouth, bringing it to a heap, on which he carefully lays his chest, or rather the pit of his stomach, and then rising up and bundling every portion of it out of the kennel. If he is put into a closed basket, he will not be still for an instant, but turn round and round without ceasing. If he is at liberty, he will seem to imagine that something is lost, and he will eagerly search round the room, and particularly every corner of it, with strange violence and indecision.
