Newyork, 12th. March, 1806.
I beg leave to lay before you a small publication concerning the Malignant Fever which has so often prevailed within a few years in various parts of the United States.
The importance of this subject, in relation to the foreign commerce of America and the social intercourse of nations, will afford, I trust, a sufficient apology for another attempt to exhibit & arrange the facts on which public opinion ought to be formed.
With sentiments of the highest respect, I have the honour to be, Sir, your most obedient and humble Servant,
DLC: Papers of Thomas Jefferson.
