ADDITIONAL NOTES ON CONTAGION. 269 



Mr. Duy, husband of the above-mentioned Mrs. Duy, was attacked sixteen days 

 after the death of his wife, viz. September 18, and died also, after an illness of sis 

 days. 



A few days after the death of Mrs. Duy, an English gentleman and his wife, of the 

 name of Fisher, who had fled from Philadelphia on account of the fever, went to board 

 with Mr. Duy, and were placed in the chamber occupied by his late wife during her ill- 

 ness : they were also attacked with fever. Mrs. Fisher was taken, September 19th, and 

 recovered in a few days, but Mr. Fisher, who was attacked four days after his wife, 

 died with the black vomit, the 27 th of September. 



At the same time, the disease re-appeared in Mrs. Johnson's family, in a young female 

 servant, who was very ill, but recovered. Soon after the attack of this girl, Mrs. John- 

 son herself was taken ill with the same disease: she had visited both of her neighbours, 

 Mrs. Duy and Mrs. Hubbs, while they were sick, she also had assorted the clothes of 

 her deceased daughter, four or five days before her own attack commenced, but had not 

 been in Philadelphia for a month. Her disorder continued eight days, and terminated 

 the 28th of September, with convulsions and the black vomit. 



A few days before the death of Mrs. Johnson, Elizabeth Stern, a woman who lived iu 

 the family, was attacked with fever, and became very yellow. Her symptoms appeared 

 moderate at first, but after lingering a fortnight she also died — The wife of a tenant of 

 Mrs. Johnson, who lived in a separate part of the house, but used the same yard, was 

 attacked before the death of Elizabeth Stern, and recovered with great difficulty. 



The last victim to be mentioned, was one Stephen Post, an old man, who lived at a 

 distance, but worked in Mr. Duy's barn, while the bed was there on which Mrs. Duy 

 died. He was also attacked with fever, and died in a few days. 



These melancholy circumstances occurred in a village which has long been remarkable 

 tor its salubrity, at a time when the other inhabitants enjoyed their usual health. In most 

 of the cases, the disease appears to have been contracted at the house of Mrs. Johnson, 

 which, before this distressing period, had been eminently distinguished by the health 

 and longevity of its inhabitants. The family were extremely neat, and it may be as- 

 serted with confidence, that the premises were never more clean than they were at the 

 lime of this truly affecting catastrophe. What cause but contagion is adequate to the 

 production of such a disease among persons so situated?
