208 ADDITIONAL NOTES ON CONTAGION. 



disease were received, added another to the list of mortality in that family ; so that in 

 the space of ten or twelve days, from the arrival of those fugitives from the city, the 

 house was swept of three of its inhabitants. 



In the preceding narrative, I have related such facts as have occurred in the circle 

 of a few miles, and I leave you at full liberty to make such use of them as you may deem 

 expedient for the public good. To resist the force of truth cannot be the object of any 

 individual of the faculty of medicine : the learning and the talents of our medical brethren 

 must render them superior to every sinister consideration, and I feel persuaded that their 

 united wish is to advance the health and happiness of their fellow creatures, and to diffuse 

 a light upon a subject, of which, to say the least, the views of physicians are extremely 

 imperfect. 



Accept, dear, Sir, the assurances of my regard, with which my mind is impressed 

 toward you, and believe me to be your friend and humble servant.

Statement of Facts tending to prove the contagions nature of the Yellow Fever, at Ger- 

 mantown, in the year 1798, by C. Wistar, M* D. Prof essor of Anatomy in the Uni- 

 versity f Pennsylvania, #c. 



The disease which produced the fatal effects now to be related, commenced in the 

 family of Elizabeth Johnson, a widow who lived in the main street of the village -of Ger- 

 mantown, about six and a half miles from Philadelphia. 



The person first affected was her child, Betsey Johnson, who had been in Philadelphia 

 from the third to the seventh of August, in a neighbourhood where several cases of the 

 fever had already appeared. She returned home the seventh, and on the ninth of the 

 same month was attacked with the yellow fever, which terminated fatally in four days, 



Fourteen days after her death, viz. August 27th, Mrs. Duy, the next neighbour of 

 Mrs. Johnson, who had visited Betsey several times during her illness, was attacked 

 with a fever supposed to be of the same kind, and died at the end of four days. 



On the thirtieth of August, the wife of Charles Hubbs, who also lived near to Mrs. 

 Johnson, and I. ad visited both Betsey and Mrs. Duy, once at least during their respective 

 indispositions, but had not been in Philadelphia for many months, was attacked with 

 unequivocal symptoms of the yellow fever, in its most malignant form, and died the 2d 

 of September.
