There are some methods peculiarly adapted to the case of a man fatigued by walking. Frequent friction, even upon the journey, relieves him; at the end of the journey first sitting down, and then unction; afterwards he may foment with warm water, or use the warm bath, rather to his lower, than his upper parts. But if any one has been scorched in the sun, he must immediately go to the bagnio, and rub over his body and head with oil, and then go down into the bath, warmed to a good degree; after that, first warm water must be poured over the head, and then cold. But he, that has been chilled with cold, must wrap himself up, and sit down in the laconicum, till he sweat; then anoint, and afterwards bathe; eat moderately, and drink wine unmixed. He that has been upon sea, and is troubled with a nausea, if he has vomited much bile, ought to abstain from food wholly, or take very little: if he has brought up acid phlegm, he may notwithstanding take food, but lighter than ordinary: if he has had a nausea without vomiting, he should abstain from food, or take a vomit after meat. He that has sat the whole day, either in a chariot or in the theatre, should by no means run, but walk slowly. It has been frequently serviceable to stay a long while in the bath, and then to sup slightly. If one grows hot in the bath, it will refresh him to take vinegar, and hold it in his mouth: if that is not at hand, cold water may be used in the same manner. Above all things it is proper to know the constitution of the body: because some are slender, others fat; some hot, others cold; some moist, others dry; some costive, and others lax. There are very few instances of men, who have not a weakness in some part or other of their body. A person of a slender habit should take methods to gain flesh, one of a plethoric should diminish his bulk; one of a hot temperament ought to cool himself, the cold to warm him; one of a humid should dry, and one of a dry should moisten; he that is loose in the belly should harden it, and he that is bound should relax; and in general, means must always be used to help that part which is most liable to disorders. [Sidenote: _The means of fattening the body._] The body is fattened by gentle exercise, frequent rest, unction, and the warm bath, if it be after dinner; a costive belly, moderate cold in the winter, a full sleep, but not over long, a soft couch, tranquillity of mind, the eating and drinking of sweet and fat things, frequent meals, and as much food as it is possible to digest.
