VI. Memoranda respecting the Influenza, whieh pre- 

 vailed in different parts of the United- States, in the 

 year 1807. Collected by Dr. William Currie 

 of Philadelphia. 



IT is reported that the Influenza prevailed at 

 Halifax, for some time before it made its appearance at 

 New. York ; and I am certain, from the intelligence 

 which I have received, from different correspondents, 

 that it had existed a fortnight, at least, in New- York', 

 before it was observed in any of the other States. 



It had made very little progress in Philadelphia on 

 the 11th of August, at which time, it appears from Dr 

 Ricketson's account, published in some of the New- 

 York newspapers, more than half the inhabitants of that 

 city were, or had been lately, affeeted by it. It disap- 

 peared in Philadelphia about the latter end of Sep- 

 tember. 



In a letter, dated August 18th, Dr. Smith informed 

 me, that the influenza had only just begun to make its 

 appearance at Wilmington, in the State of Delaware, 

 which is only twenty-seven miles from Philadelphia.
