Many of those who are violently disordered will continue particular actions for a considerable time: some are heard to gingle the chain, with which they are confined, for hours without intermission; others, who are secured in an erect posture, will beat the ground with their feet the greatest part of the day. Upon enquiry of such patients, after they have recovered, they have assured me that these actions afforded them considerable relief. We often surprize persons who are supposed free from any mental derangement, in many strange and ridiculous movements, particularly if their minds be intently occupied:[7]--this does not appear to be so much the effect of habit, as of a particular state of mind. Among the bodily particularities which mark this disease, may be observed the protruded, and oftentimes glistening eye, and a peculiar cast of countenance, which, however, cannot be described. In some, an appearance takes place which has not hitherto been noticed by authors. This is a relaxation of the integuments of the cranium, by which they may be wrinkled, or rather gathered up by the hand to a considerable degree. It is generally most remarkable on the posterior part of the scalp; as far as my enquiries have reached, it does not take place in the beginning of the disease, but after a raving paroxysm of some continuance. It has been frequently accompanied with contraction of the iris. On the suggestion of a medical gentleman, I was induced to ascertain the prevailing complexion and colour of the hair in insane patients. Out of two hundred and sixty-five who were examined, two hundred and five were of a swarthy complexion, with dark, or black hair; the remaining sixty were of a fair skin, and light, brown, or redhaired. What connexion this proportion may have, with the complexion and colour of the hair of the people of this country in general, and what alterations may have been produced by age, or a residence in other climates, I am totally uninformed. Of the power which maniacs possess of resisting cold, the belief is general, and the histories which are on record are truly wonderful: it is not my wish to disbelieve, nor my intention to dispute them; it is proper, however, to state that the patients in Bethlem Hospital possess no such exemption from the effects of severe cold. They are particularly subject to mortifications of the feet; and this fact is so well established from former accidents, that there is an express order of the house, that every patient, under strict confinement, shall have his feet examined morning and evening in the cold weather by the keeper, and also have them constantly wrapped in flannel; and those who are permitted to go about, are always to be found as near to the fire as they can get, during the winter season.
