If the appearances already described are observed early, a very favourable event is implied: but it happens in some cases, although it may be perceived that the inoculation has succeeded, yet it is barely perceptible; the colour about the wound remaining pale, instead of changing to red or inflamed; the edges of the incision spread but little, they remain flat, scarcely rising at all, and are attended neither with itching or uneasiness of any kind. Nay, sometimes on the fifth, and even the sixth-day, the alteration is so little, as to make it doubtful whether the infection has taken place. When matters are in this state, the appearance is unfavourable, and implies a late and more untoward disease: to prevent which, I direct the powder or pill to be taken each night; and in case it fails to operate by stool, or there is the least disposition to costiveness, an ounce of Glauber’s salts, or more commonly the laxative draught already mentioned, is given in the morning, once or twice, as the case may require. This course forwards the inflammation, which I always wish to see; as I have constantly observed, that an early progress on the arm, and an early commencement of the eruptive complaints, portend that the distemper will be mild and favourable; and on the contrary, where both are late, the symptoms are usually more irregular and untoward. Being now arrived at the most interesting period of this distemper, the eruption, a period in which the present practice I am about to recommend, differs essentially from the method heretofore in use, and on the right management of which much depends, it will be requisite to give clear and explicit directions on this head, and to advise their being pursued with firmness and moderation. Instead of confining the patient to his bed, or his room, when the symptoms of the eruptive fever come on, he is directed, as soon as the purging medicine has operated, to keep abroad in the open air, be it ever so cold, as much as he can bear, and to drink cold water, if thirsty; always taking care not to stand still, but to walk about moderately, while abroad.
