At this time _Count Gregory Orlow_[22] arrived at Moscow, invested with full powers by the empress. I received an order, in common with the other physicians, to deliver, in writing, my private sentiments on the subject; we were required to turn our attention principally to the most proper measures for destroying the contagion[23]. Having taken the necessary steps to prevent all further popular commotions, the Count selected, from all our papers, what appeared of most moment, and drew up a set of regulations, as well for the treatment of the sick, as for the keeping of those who were yet well, free from infection. He also ordered new hospitals to be immediately built for the reception of the poor seized with the plague[24]. Some months had elapsed since the plague had been carried to many of the villages, as well in the vicinity as at a distance from Moscow. Persons who fled from this city had also carried it with them to Kalomna (Kaluga, according to _Orræus_), Yaroslaw, and Tula. Inspectors of health, attended by physicians and surgeons, were sent to these infected towns and villages. A Council of Health was formed, composed of _General Yeropkin_ (who was president), of some counsellors of state, and of three physicians, and one surgeon. This council received daily reports from the physicians and police-officers, and took cognizance of every thing which related to the health of the inhabitants. Two physicians, Drs. _Pogaretzky_ and _Meltzer_, being offered a reward of one thousand roubles, undertook, each of them, the care of a pest-hospital; and went thither accordingly. On the 10th of October the frost set in; from that day the disorder was less fatal, and the contagion became more fixed. The number of sick and dead gradually diminished; and the disorder, which a short time before had terminated on the second or third day, now kept on to the fifth or sixth. Neither those large purple spots, which we have before described, nor carbuncles, were by any means so frequent as they had been; buboes were now almost the only tumours found upon the infected. The hard frost[25] which prevailed during the two last months of the year, weakened the pestilential virus to such a degree, that those who attended the sick and buried the dead were in much less danger of being infected; and when they were infected, the symptoms were much milder; so that at this period, several persons who had the plague were but slightly indisposed, and walked about though they had buboes upon them. At the close of the year 1771, this dreadful scourge ceased, by the blessing of God, at Moscow, and in every other part of the Russian empire. Besides the three towns before-mentioned, upwards of four hundred villages had been infected.
