Monticello Augt. 27th 1827
When I had the pleasure of visiting Montpellier last year, I promised Mr. Payne to send him some vaccine matters so soon as I could obtain any: the enclosed is the first I have been able to recommend—You will oblige me by placing it in his hands. The only plan to be adopted in using it is merely to moisten it with cold water & to cover the point of the lancet well with the solution.
Mrs. Dunglison unites with me in kind regards to Mrs. Madison. Very respectfully
