During my intercourse with the sick, I felt the miasmata of the fever operate upon my system in the most sensible manner. It produced languor, a pain in my head, and sickness at my stomach. A sighing attended me occasionally, for upwards of two weeks. This symptom left me suddenly, and was succeeded by a hoarseness, and, at times, with such a feebleness in my voice as to make speaking painful to me. Having observed this affection of the trachea to be a precursor of the fever in several cases, it kept me under daily apprehensions of being confined by it. It gradually went off after the first of October. I ascribed my recovery from it, and a sudden diminution of the effects of the miasmata upon my system, to a change produced in the atmosphere by the rain which fell on that day. The peculiar matter emitted by the breath or perspiration of persons affected by this fever, induced a sneezing in Dr. Dobell, every time he went into a sick room. Ambrose Parey says the same thing occurred to him, upon entering the room of patients confined by the plague. The gutters emitted, in many places, a sulphureous smell during the prevalence of the fever. Upon rubbing my hands together I could at any time excite a similar smell in them. I have taken notice of this effect of the matters which produced the disease upon the body, in the year 1794. In order to prevent an attack of the fever, I carefully avoided all its exciting causes. I reduced my diet, and lived sparingly upon tea, coffee, milk, and the common fruits and garden vegetables of the season, with a small quantity of salted meat, and smoked herring. My drinks were milk and water, weak claret and water, and weak porter and water. I sheltered myself as much as possible from the rays of the sun, and from the action of the evening air, and accommodated my dress to the changes in the temperature of the atmosphere. By similar means, I have reason to believe, many hundred people escaped the disease, who were constantly exposed to it. The number of deaths by the fever, in the months of August, September, and October, amounted to between ten and eleven hundred. In the list of the dead were nine practitioners of physic, several of whom were gentlemen of the most respectable characters. This number will be thought considerable when it is added, that not more than three or four and twenty physicians attended patients in the disease. Of the survivors of that number, eight were affected with the fever. This extraordinary mortality and sickness among the physicians must be ascribed to their uncommon fatigue in attending upon the sick, and to their inability to command their time and labours, so as to avoid the exciting causes of the fever.
