His precepts respecting the sweat are very appropriate, for he gives a caution against forcing perspiration, prescribes according to the circumstances, and even commences the treatment with an emetic, if the state of the stomach seems to indicate its employment. In order to guard against contagion, he recommends, at the approaching autumnal fair, that foreigners from “_dying lands_” _should be accommodated in distinct inns_, that fumigation should be carefully employed, and that before each booth at the fair a fire should be kept up. Another pamphlet by Caspar Kegeler, of Leipzig, is a melancholy monument of the credulity which, from Herophilus to the present day, has pervaded the whole medical art. It is a regular pharmacopœia for the Sweating Sickness, thrown together at a venture, without any insight into the nature of the disease. A mine of wonderful pills and electuaries composed of numberless ingredients wherewith this “mysterious worthy” undertakes to raise a commotion in the bodies of his patients. If he had but seen even a single case of the disease he would at least have known how impossible it would be to administer, within the space of four-and-twenty hours, the hundredth part of his pills and draughts. With what approbation this little pharmacopœia was received by physicians of equal penetration and understanding as himself, is shewn by the eight editions which it passed through[652], and the melancholy reflection is therefore forced upon us, that possibly thousands of sick persons were maltreated and sacrificed from the employment of Kegeler’s medicines. A third physician at Leipzig, Dr. John Hellwetter, states in his pamphlet, that he has become acquainted with the Sweating Fever in foreign countries, and on the subject of perspiration gives some very good advice, evidently the result of his own experience, which reminds us of the original English mode of treatment. His notion that fish is injurious seems to have originated in the fact that the continued employment of fish as an article of diet gives rise to offensive perspirations, and his admonition to his medical brethren not to flee from the sick, but to visit them sedulously and give them consolation, furnishes ground for supposing that some of them had been pusillanimous and dishonourable enough to withdraw themselves or to refuse their assistance to the poor.
