for the most part, merely the habits acquired of irregularly expending their nervous energy, which fluctuations are further increased by the usual atmospheric causes of excitement and depression The influence of temperature, moisture, climate, seasons, 129 diurnal periods, atmospheric changes, and different years, on our health and spirits, and the type of our diseases, (and that this subject will be resumed), and how all this is modified by the states, habits, and circumstances of the insane Why they are less subject to the prevailing diseases 133 The mental condition must, in all diseases, be considered 134 Illustrated by cases 135 How the state of mind and circumstances of the insane must 136 modify these physical influences Why this is differently exhibited by the insane, than it is 137 by those who retain the power over their own spirits That this view is proved to be correct, by the fact that 139 these causes produce different effects by their being under different modes of treatment That the various character of insanity is but the same 143 excitement of the vital energies operating on different parts of the mind, according to previous or present habits and states Hence, the insane are often caracatures of their own, as 146 well as of family habits and character The truth of this reasoning proved by the fact, that the 147 greatest number of insane cases occur when mental conflicts and worldly struggles are greatest, and among those whose minds are ill regulated or miserably circumstanced; but still it does not necessarily and always follow that those whose minds are most wicked are soonest overthrown, but sometimes the reverse The practical object of these observations 150 Case No. 8.—One of the extreme cases of furious mania, with 151 a leprous eruption of the skin Observation 6th.—Whether cutaneous disorders are common to 153 the insane?
