On the Return of the Troops from the Winter Expedition into the Country of _Hesse_, in the Year 1761, we had several Men seized with Inflammatory Fevers without any topical Inflammation; and at the Opening of each Campaign had always Numbers sent to the Hospitals ill of this Disorder. Towards the End of the Campaigns, and throughout the Winter, many were seized with Inflammatory Fevers; but these were mostly complicated, with pleuritic, or peripneumonic Symptoms, or other topical Inflammations, or with rheumatic Complaints. In the Inflammatory Fever, the Sick were seized at first with cold and hot Fits, succeeded by Pain in the Head and all over the Body. The Pulse was strong and quick, and the Blood sizy; attended with other Appearances commonly observed in such Fevers. As the Summer advanced, this Fever was often accompanied with bilious Symptoms, with Sickness, and vomiting of bilious Matter, and very frequently with a Purging: Towards the End of Summer it ceased, and was succeeded by the bilious remittent Fever.--And it was no uncommon Thing to see those Fevers, which originally were entirely of an inflammatory Nature, after the sick had been some Days in a crowded Hospital, partake a good deal of the Nature of the Malignant Fever, or be changed entirely into it. We treated these Fevers in the common antiphlogistic Method.--We blooded freely in the Beginning; gave the saline Draughts with Nitre and other cooling Medicines; and made the Patients drink plentifully of small Liquors:--And when they were inclined to be costive, gave mild Purges, or emollient laxative Clysters. We afterwards applied Blisters; and if the Pulse began to sink, gave Cordials, Wine, and other Remedies commonly employed in such Cases;--and towards the Decline of the Fever endeavoured to promote such Evacuations as were pointed out by Nature, and likely to prove critical. When the Case was complicated with bilious Symptoms in the Beginning, we were obliged to have particular Regard to the first Passages. If the Patient complained much of Sickness, we gave a gentle Vomit in the Evening, after bleeding; and a Purge next Day, to carry off any bilious or corrupted Humours that might be lodged in the Stomach or Intestines; and we found that these Evacuations gave Relief, and generally mitigated all the Symptoms. If at any Time during the Fever a Looseness came on, especially when attended with Gripes, we gave a Dose of some gentle Physic, which made a free Evacuation; and an Opiate in the Evening after its Operation; and afterwards we found it answer better to attempt rather to moderate, than wholly stop the Purging by strong Astringents, and Opiates; unless where the Evacuation by Stool was so great as to be in Danger of sinking the Patient. The _pulvis antimonialis_, composed of ten Parts of the _pulvis e chelis_, and one Part of the Tartar emetic, given in small Doses, was serviceable in many of these Fevers, after free Evacuations had been made.
