The old man suffering from rheumatism or gout conceives himself to be formed of china or glass, and the foxhunter tallyhos! at each new moon, as though he were following a pack. In like manner, the naturally cruel man, if the least affected in his brain, will suppose himself to be transformed into the most cruel and bloodthirsty animal with which he is acquainted.
The hallucinations under which lycanthropists suffered may have arisen from various causes. The older writers, as Forestus and Burton, regard the were-wolf mania as a species of melancholy madness, and some do not deem it necessary for the patient to believe in his transformation for them to regard him as a lycanthropist.
In the present state of medical knowledge, we know that very different conditions may give rise to hallucinations.
In fever cases the sensibility is so disturbed that the patient is often deceived as to the space occupied by his limbs, and he supposes them to be preternaturally distended or contracted. In the case of typhus, it is not uncommon for the sick person, with deranged nervous system, to believe himself to be double in the bed, or to be severed in half, or to have lost his limbs.
