So that if five patients produce a given ratio of pestilence, ten will produce, not as much again, but nearly a hundred times as much, And hence we may readily account for the fearful and deadly ravage which this cruel scourge is well known to inflict upon a people when closely pressed together, and incapable of flying from its pestilential aura, as in crowded encampments, or a besieged and pent-up town: and especially where, as is often the case, there is considerable carnage from the casualties of war, and a deadly calm prevails for weeks together in the atmosphere. This last concomitant, indeed, gives completion to the whole; and is a heavier calamity than it is generally conceived to be; for the most fatal pestilences of which we have any account seem to have been preceded by a stagnant atmosphere. Thus, Maitland, in his History of London, observes, that for, several weeks before the plague broke out in this metropolis in 1665, there was an uninterrupted calm, without sufficient motion in the air to turn a vane.” The assertion is confirmed by Baynard, a contemporary physician; and a like harbinger, as is observed by Diemerbroeck, preceded the plague at Nimeguen..

On this account whatever tends to weaken the animal frame generally, or any one of its functions particularly, must, as a common rule, be carefully abstained from : and hence severe evacuations, by bleeding or purging, are among the foremost objects of prohibition.

If in the first, there will be a sense of oppression in the brain, most commonly combined with stupor, or low muttering delirium; if in the second, a laborious weight on the chest and a difficulty of respiration; if in the third, the bowels will usually be found costive, the motions pale and argillaceous, and sometimes the skin and the urine chlorotic, or of a greenish-sallow from a regurgitation of bile, morbidly secreted, into the sanguineous system.
