Soldiers generally enjoy good Health in cold dry Weather, even during the Time of severe Frost; if they be kept in Exercise, be well cloathed, and well supplied with Provisions and good Liquors, and with Wood; as the Troops, both in _Germany_ and _North America_, experienced during the late War; but Cold joined to Moisture was observed always to be productive of Diseases. Nor is mere Heat of itself such an Enemy to Health[117] as is generally apprehended; but when joined to Moisture, is observed to give Rise to the most fatal Disorders in the warm Climates. [117] This Dr. _Pringle_ takes Notice of; and Mr. _Naesmith_ says, he observed it in Voyages to the _East Indies_, which afford the fairest Trials of this Kind. See Dr. _Lind’s Essay on the Means of Preserving the Health of Seamen_, 2d edit. note to page 5. In our northern Climates the Winters are cold, and the Weather variable; sometimes it is cold and rainy, at other Times thick and foggy; sometimes we have fair Weather and Sunshine, at other Times Frost and Snow; and sometimes it happens that we have all these different Sorts of Weather in the same Day. During this Season, Soldiers are subject to Coughs, Pleurisies, Peripneumonies, Rheumatisms, and other Disorders of the inflammatory Kind. And in very intense Frost, they are liable to have their Limbs benumbed with Cold, and their Extremities Frost bit (as it is called). And where there is a Want of fresh Provisions, and they are obliged to live on salted Meat, and cannot have Greens, Pot Herbs, Roots, or other fresh Vegetables, nor be properly supplied with Beer, Cyder, Wine, or other generous fermented Liquors, they, as well as Sailors, are subject to the Scurvy[118]; especially if they be encamped or quartered in low damp Places. [118] Dr. _Joh. Valint. Willius_, Army Physician to the King of _Denmark_, in his Treatise on Camp Diseases, says, you scarce find a Camp in these northern Countries in which the true Scurvy, attended with stinking Breath and eroded Gums, is not to be observed. _Cap._ iii. _sect._ iii. The best Means of guarding against inflammatory Disorders, and other Mischiefs arising from Cold, whether in Camp or in Quarters, is, to take Care that the Soldiers be well cloathed; that they lie dry, and be well provided with Straw and Blankets, and with Wood; and to prevent, as much as possible, their exposing themselves to sudden changes from Heat to Cold.
