On the 11th of March we are again convened at the Board of Health. In the centre of the town there was a large building used for manufacturing clothing for the army; three thousand persons were employed in it, nearly a third part of whom, of the most necessitous class, occupied the ground-floors; the rest, after working there the whole day, returned in the evening to their respective homes, in different parts of the town. Dr. _Yagelsky_, at that time second physician to the Military Hospital, whom the Governor-General had sent to the manufactory in the morning, brings word that he had found several patients, (eight to the best of my recollection) labouring under the same disorder, (accompanied with petechiæ, vibices, carbuncles, and buboes) which he had seen three months before at the military hospital; and that on seven dead bodies which he had examined, he had perceived similar appearances. On enquiring of the workmen in the manufactory, in what manner, and how long this disorder had made its appearance among them, he was told that a woman who had a swelling in her cheek, had betaken herself to one of her relations who lived in the manufactory, and had died there; and that, from that time, one or other of them was every day taken ill of the disorder. They further stated, that from the period above-mentioned to the present day, they had lost one hundred and seventeen persons, including the seven dead bodies not yet interred. This account given by Dr. _Yagelsky_, was corroborated by two other physicians, who had been sent the same day to examine the patients and dead bodies. In a Memoir addressed to the Governor-General and the Senate (by whom we had been called together) we renew our declarations, that this disorder is the plague[13]; and we advise them to remove out of the town all the persons dwelling in the manufactory, taking care to separate the sick from the healthy; that they should order the clothes and furniture of the dead and infected to be burnt; and that the strictest search should be made to find out whether the contagion existed in any other part of the city. The inhabitants are again seized with a panic; and they now too well perceive the consequences of their neglect of the precautions recommended. We were thirteen physicians at this meeting[14], two of whom, who three months before had agreed with us that the disease which broke out at the military hospital was the plague, now said that the present disorder was not the plague, but a putrid fever; an opinion which they enforced in a separate conference with the Senate. These two physicians (Drs. _Kuhlmann_ and _Schiadan_) who still differed from us in opinion, had been led into their error, by observing that the number of deaths in the town was not greater than usual, but rather less than in the preceding years, and that there were very few people ill.
