Many of the Patients, towards the Height of this Fever, sooner or later, had a Purging, which seldom proved critical; and some were seized with the Flux. A gentle _diarrhœa_, such as did not sink the Patient, was commonly of Service; but when violent, or a Dysentery came on, the Case was always dangerous; for whatever stopped the Flux increased the Fever; and, if the Purging or Flux continued, it sunk the Patient. Such Fluxes we treated in the Manner to be mentioned afterwards, when we come to the History of the Dysentery. In this Fever, it was common for Patients to vomit Worms[14], or to pass them by Stool, or, what was more frequent, to have them come up into their Throat and Mouth, or sometimes into their Nostrils, while they were asleep in Bed, and to pull them out with their Fingers. The same Thing happened to most of the _British_ Soldiers, brought to the Hospitals for other feverish Disorders as well as this. Dr. _Pringle_[15] when he mentions Worms being observed in this Fever, seems to embrace _Lancisius_’s Opinion; and believes that these Worms are not the Cause of the Fever; but being lodged in the Intestines, before the Fever comes on, they are annoyed by the Increase of the Heat, and the Corruption of the Humours, in the Cavity of the Intestines of Persons labouring under Fevers, especially of the putrid Kind; and so they begin to move and struggle to get out. This seemed evidently to be the Case with many of the Patients we had; though in some the Worms seemed to have given Rise to the Fever, which the bad State of the Patient’s Humours, or the infected Air of Hospitals, determined to be of this Kind. In many, the Fever lessened, or went off entirely, soon after; and they were no more affected with Symptoms of Worms. But some notwithstanding were subject to frequent Sickness, Pain of the Stomach, and Uneasiness in the Bowels, and discharged some Worms from Time to Time. Others had frequent Relapses into Fevers, which seemed to be owing to the Irritation of these Insects. [14] Some Men passed only one Worm; others, two or three; some, six or seven; and one Man, of the Guards, in _January_ 1763, after passing three by Stools in the Course of a Fever of this Kind, discharged fourteen more upon taking a Dose of Rhubarb and Calomel after the Fever was over.

It is no Wonder that Worms of the round Kind should be productive of troublesome Symptoms, and occasion these Relapses; since we know that they have sometimes perforated the Intestines, and been found in the Cavity of the Abdomen[16].
