symptoms were considerable, and I never, in any one instance, was attacked with Night-Mare under those circumstances. There is no circumstance to which the sufferers under this disease ought to pay more attention than to their sleep, for every irregularity in this particular, will increase the violence of the disease. It is almost always produced by sleeping too long, frequently by sleeping too sound, and generally after having lain long awake in the night. These things ought therefore to be carefully avoided. Going to bed before the usual hour is a frequent cause of Night-Mare, as it either occasions the patient to sleep too long, or to lie awake in the night. Passing a whole night, or part of a night, without rest, likewise gives birth to the disease, as it occasions the patient on the succeeding night to sleep too sound. Indulging in sleep too late in the morning is an almost certain method to bring on the paroxysm; and it should be remembered, that the more frequently the paroxysm returns, the greater strength it acquires. I am aware that the propensity to sleep is at this time almost irresistible, and indeed, without rising from bed, it is altogether so; but a little resolution is required to be employed here. Those who are habitually subject to the attacks of Night-Mare ought never to sleep alone, but to have always some person near them and within reach, so as to be immediately awoke by their groans or struggles; and the person to whom this office may be entrusted, should be instructed to rouse the patient as early as possible, that the paroxysm may not have time to gain strength; for the frequent repetition of the paroxysms gives greater strength to the disease, and that in proportion to the length of their duration. A long and obstinate paroxysm of Night-Mare will be found to differ not much from Epilepsy, and I have seen some to which it would be difficult to apply the proper appellation. The patient cannot pay too much attention to this circumstance, that is, the prevention, as much as possible, of the paroxysms: _crescit eundo_. If he has not the means at hand of preventing the paroxysms when they make their appearance, it will be better to rise and walk about for an hour, or until the sense of weight about the præcordia shall have disappeared. I have before observed, that any thing which will procure the discharge of a quantity of wind from the stomach, will for the time, put off the return of Night-Mare: I have frequently effected it by a glass of common gin, when nothing else was at hand; but either of the draughts, No. 1 or 2, will more effectually answer the purpose, and for that reason should be kept in readiness by such as are frequent sufferers from this disease. But it is not the temporary relief from the paroxysms merely, that the patient ought to keep in view, but the permanent amendment of his constitution, and the preventing, as much as possible, the formation of that trash in the alimentary canal,
