The year 1835, was the most sickly year, for common intermittents, _which prevailed more amongst the old settlers, than the newly arrived emigrants_. In Illinois, and generally throughout the West, below the fortieth degree of latitude, it was sickly, though not fatal. Early in the spring, till the month of May, it was unusually dry, and vegetation was two weeks later than usual. May and a part of June were very wet, followed by a few days of extremely hot weather. Vegetation grew with great luxuriance. Newly ploughed ground sent forth a noxious effluvium, with a most offensive odour, and after a few days would be covered with a greenish coat, like the scum on stagnant water. Town situations, even along the banks of river, were comparatively healthy.
In case of sickness, physicians are to be found in almost every county, and every season adds to their number. Charges are somewhat higher than in the northern states. Many families keep a few simple articles of medicine, and administer for themselves. Calomel is a specific; and is taken by multitudes without hesitation, or fear of danger. From fifteen to twenty grains are an ordinary dose for a cathartic. Whenever nausea of the stomach, pains in the limbs, and yawning, or a chill, indicate the approach of disease, a dose of calomel is taken at night, in a little apple honey, or other suitable substance, and followed up in the morning with a dose of castor oil, or salts, to produce a brisk purge. Sometimes an emetic is preferred. Either a cathartic or an emetic will leave the system under some debility. The mistake frequently made is, in not following up the evacuating medicine with tonics. This should be done invariably, unless the paroxysm of fever has commenced. A few doses of sulphate of quinine or Peruvian bark in its crude state, will restore the system to its natural tone. To prevent an attack of fever, medicine should be taken on the very first symptoms of a diseased stomach; it should not be tampered with, but taken in sufficient doses to relieve the system from morbid effects, and then followed up by tonics, to restore its vigor and prevent relapse.
New comers will find it advantageous for protecting themselves from the damp atmosphere at night, to provide close dwellings; yet when the air is clear, to leave open doors and windows at night for free circulation, but not to sleep directly in the current of air; and invariably to wear thin clothing in the heat of the day, and put on thicker garments at night, and in wet and cloudy weather.
