Of-the Cure of Intermittent Fevers.

228. It still remains to consider the cure of intermittent fevers; and with respect to these, we form also three general indications.

1. In the time of. intermission, to prevent the recurrence cf paroxysms.

1, In the time oj paroxysms, to conduct these so as to obtain a final solution of the disease.

3, To take off certain circumstances which might prevent the fulfilling of the two first indications.

229. The first indication maybe answered in two ways.

1, By increasing the action of the heart and arteries semetime before the period of accession, and supporting that increased acrion till the period of the accession be over, so as thereby to prevent the recurrence of the atony and spasm of the extreme vessels which give occasion tp the recurrence of paroxysms.

2, Without increasing the action of the heart and arteries, the recurrence of paroxysms may be prevented, by supporting the tone of the vessels, and thereby preventing atony, and the consequent spasm.

230. For the purpose mentioned in 229, 1, the action of the heart and arteries may be increased.

1, By various stimulant remedies, internally given, or externally applied, and that without exciting sweat. ,

2, By the same remedies, or others so managed as to excite sweating, and to support that sweating till the period of accession be for sometime past.

3, By nauseating doses of emetics, given about an hour before the time of accession, thereby supporting and increasing the tone and action of the extreme vessels.

231. The tone of the extreme vessels may be Supported without increasing the action of the


heart and arteries (229, 2), by various tonic medicines; as,

1, Astringents alone;

2, Bitters alone;

3, Astringents and bitters conjoined; *

4, Astringents and aromatics conjoined;

5, Certain metallic tonics;

6, Opiates;

Lastly, an impression of horror. •

A good deal of exercise, and as full a diet as the condition of the patient's appetite and digestion may allow of, will be proper during the time of intermission, and may be considered as belonging to this head.

232. Of all the tonic remedies mentioned (231), the most celebrated, and perhaps the most certainly effectual, is the Peruvian bark, the tonic power of which we have endeavoured to demonstrate above (214), and have, at the same time, explained its use in continued fevers.

The same observation as made in 216, is especially proper in the case of intermittents: and further, with respect to these, the following observations or rules are offered here.

1, That the bark may be employed with safety at any period of intermittent fevers,' providing that, at the same time, there be neither a phlogistic diathesis prevailing in the system, nor any considerable or fixed congestion present in the abdo-r minal viscera.
