“ thus,--“This beneficial practice is patronised by jefferson in the new world, & by the emperor of germany, the empress dowager of russia in the old” . . .

"A second edition of this Treatise will I believe follow in a few months, before which I hope to receive from my friends & correspondents such corrections, hints for additions, or omissions as will make it less exceptionable to the scholar & physician . . .”

This letter was received by Jefferson on March 18. On March 21 he wrote from Monticello to Waterhouse: “ Th: Jefferson returns his acknolegements to Doct ^r. Waterhouse for his letter of the 1 ^st. inst. & the book accompanying it, which he recieved & will have the pleasure of perusing here, where he is on a visit of a fortnight, engaged in the rural operations of the season. the small pox having got into a neighborhood about 30. miles from this, he was enabled yesterday, with some vaccine matter he brought from Washington, to inoculate a large deputation of persons from that neighborhood, and thus to communicate the blessing for which they are indebted to D ^r. Waterhouse . . . ”

This part contains numerous references to Thomas Jefferson and to his activities in establishing the practice of vaccination in the United States. On page 22 is quoted in full the letter from Jefferson to Waterhouse written on December 25, 1800 (see the previous entry). Pages 23-29 contain a letter from Waterhouse to Thomas Jefferson dated June 8, 1801. With this letter Waterhouse enclosed Aikin’s book on the same subject, see no. 955. On page 32-34 is quoted a letter from “President Jefferson to Mr. Vaughn, printed in Dr. Coxe’s pamphlet on Vaccination.”

Other references to Jefferson occur.

The dedication of Part II reads: To John Coakley Lettsom; and to Edward Jenner; Physicians preeminently distinguished for their active benevolence and professional skill, this Essay is inscribed, as a mark of Esteem and Respect, by their transatlantic Friend Benjamin Waterhouse. Cambridge New England, November 1802.

Benjamin Waterhouse, 1754-1846, American physician, a native of Newport, Rhode Island, was a member of the American Philosophical Society and many other learned institutions. He was the pioneer vaccinator of America, and was enabled to carry on his experiments and to establish the practice owing to the enthusiastic support of Thomas Jefferson.

Several tracts on vaccination were published by this Society during the years 1801-1803, any or all of which may have been owned by Jefferson.

Jefferson’s copy was sent to him by the Society.

On July 4, 1803, Charles Murray, Secretary of the Royal Jennerian Society[,] wrote to Jefferson: “I have the honour, by the direction of the Royal Jennerian Society for the Extermination of the Small pox, to entreat your acceptance of the Society’s Address and it’s other publications.

"The ardour already manifested in the United States in promoting the Vaccine Inoculation, and the progress which it has made there under your auspices, sufficiently evince Sir, that no inducements are wanting to engage you in this great cause of benevolence . . .”
