Strangury, though often the effects of blisters, sometimes occurs in fevers without their application, and arises from a spasmodic irritation of the neck of the bladder. In this case opium, particularly in clysters, is the most effectual remedy.

Haemorrhages sometimes occur in fevers, which occasion no little difficulty. If the pulse be full and hard; if much headach has preceded; if faintness does not follow the evacuation; but, on the contrary, the pulse becomes softer and slower; the bleeding may go on. If it happen at the conclusion of fever, and be attended with faintness, it is highly dangerous. Cold, bark, and the mineral acids, have been accounted the best remedies; but even in this low state we have found nitre successful in repeated doses. It is indeed one form of employing cold. See Haemorrhagiae.

Longings for particular foods are sometimes troublesome. These must be distinguished from the caprice of the moment; and if the patient continue to desire, with much anxiety, any particular food, we have found that he may be more safely indulged than contradicted, even should the desired food appear highly injurious. We have known wine anxiously longed for; and a very large quantity drunk in a short time, not only with impunity, but advantage.

Among the sequelae of fever are cough, night sweats, an irritable and irregular state of mind, a capricious and often an inordinate appetite. These are, in general, marks of debility only, and disappear with returning strength. Bark and tonics are usually employed for a time with little effect. The constitutional powers are at last exerted, and the patient gains in hours the strength which, with the most powerful tonics, it did not attain in days. The powers of digestion, however, do not return in the same proportion as the appetite, and relapses are not uncommon from unlimited indulgence.

The great varieties of fevers we shall in a future part of this work endeavour to bring within more strict limits. It would be to anticipate what can only be then detailed with advantage to add any thing at present on the subject, and We shall of course preserve the various references in the former edition with little change.
