There is also another distemper, which in a different way is opposite to the phrenitic one. In phrensies sleep is hardly obtained, there is a disposition to fool-hardy enterprises: in this there is a languor, and an almost invincible necessity of sleeping. The Greeks call it lethargus[ BI ]. This too is of the acute kind, and unless it is cured, kills quickly.

Therefore some endeavour to rouse such patients by holding to their nose those things, which provoke sneezings, and such as excite by their offensive smell; for instance, burnt pitch, sordid wool, pepper, hellebore, castor, vinegar, garlick, onion. They also burn galbanum by them, or hartshorn; if this is not to be got, any other horn; for when these are burnt, they stimulate by their offensive smell.

But a certain author, Tharrias, affirmed, that this disposition to sleep is concomitant upon a febrile paroxysm, and that it abates, when the latter is gone off: and therefore that such practitioners, as rouse them frequently, give them unnecessary pain. Now it makes a considerable difference whether the patient awakes upon the termination of the fit, or whether the weight of sleep oppresses him, when the fever is abating, or even after its going off. For if he awakes, it is needless to treat him as one asleep: for he is not made better by being awake; but if he be better, he will keep awake of himself. If his sleep is continual, he must in such a case be roused; but at those times, when the fever is lowest, that he may discharge somewhat, and take food. Cold water suddenly poured on excites more powerfully than any thing. After the remission therefore the whole body must be anointed over with a great quantity of oil, and three or four amphorae of water must be poured upon the head, so as to stream over all the body. But this we shall make use of, if the patient’s breathing be equal, if the præcordia be soft. But if the case shall be different, the other remedies are preferable, which were mentioned before. And as to the sleep, this method is the most suitable.

With regard to the cure of the distemper, the head must be shaved; then fomented with a decoction of bay-leaves, or of rue in vinegar and water. And the day after, castor must be applied, or rue bruised with vinegar, or bay-berries, or ivy with rose-oil and vinegar. And mustard is of singular use, both held to the nostrils in rouzing the patient, and if applied to the top of the head or forehead, in removing the distemper itself. Gestation is also useful in this distemper, and especially food seasonably given, that is, in the greatest remission, that can be found. Now gruel is most proper till the distemper begins to decline. And if every day there is a severe fit, this may be given daily: if every other day, gruel after the most severe; after the milder hydromel. Wine also given with seasonable food is of no small use.

But if such a torpor has come after long fevers, all the other rules are to be observed: but three or four hours before the fit, if the belly be bound, castor with a mixture of scammony must be given; if that is not the case, castor alone must be given with water. If the præcordia are soft, the diet must be pretty full; if hard, we must keep to the gruels above-mentioned; something being applied to the præcordia, which can at once repel and soften.
