But if the distemper is more violent, and there is a true phthisis, it is necessary to oppose its beginnings: for if this distemper continue long, it is not easily overcome. If the patient’s strength allow, he must take a long voyage, change his climate, taking care to remove into a grosser air, than that he leaves; and therefore from Italy to Alexandria is a very agreeable change. And generally at the beginning the body may be well supposed able to stand that fatigue, since this distemper generally comes on at the strongest age, that is, from the eighteenth year to the thirty-fifth. If the weakness will not admit of that, it is very proper however to sail in a ship, but not far. But if any circumstance render the sailing unfit, the body must be moved in a litter or some other way; then business must be laid aside, and every thing, which disturbs the mind; sleep must be indulged; catarrhs avoided, lest they exasperate, what may have been mitigated by care; and for that reason crudity must be guarded against, and at the same time both the heat of the sun and cold, the face defended, the throat wrapped up, and the cough removed by its peculiar remedies. And as long as the fever continues to attack, it must be treated sometimes by abstinence, sometimes also by seasonable food: and at such time water must be drunk. Milk likewise, which is poison in pains of the head, and acute fevers, and excessive thirst, occasioned by these, and when the præcordia are swelled, or the urine is bilious, or in hæmorrhages; yet in a phthisis, as well as in all tedious and obstinate febriculas, it may very well be given. But if a fever does not yet come on, or has already remitted, recourse must be had to moderate exercise, and especially walking and gentle friction. The bath is hurtful. The food at first ought to be pungent, such as garlick, leeks, and the same in vinegar, or in the same way endive, basil, lettuce; afterwards mild, as gruel(36) made from ptisan, or alica, or from starch, with the addition of milk. Rice also, and, if there is nothing else, far will answer the same end. Then these two sorts of food are to be alternately used; and something of the middle kind is to be added, and especially brains(37), and small fish, and such like. Flour also mixed with mutton or goat’s suet, and boiled, serves for a medicine. Wine ought to be taken light and austere.
