In the interview at your house and during the very interesting remarks with which you favoured me on that occasion, the conversation turned on the subject of Galvanism—I mentioned some experiments performed in this place and offered to send them for your perusal—Mrs Madison kindly offering to read them to you—A favorable opportunity presenting itself by a gentleman going to Orange C H. I send the narrative of the experiments for your perusal with the hope that you will find them interesting—The subject of Galvanism, Electricity & Magnetism are probably yet in their infancy and the world will be indebted to some future Franklin or Davy for discoveries far surpassing those already made by these truly great men—In connection with those experiments, I send a small Essay on the Nervous System which will explain the situation of those parts alluded to in the course of the Experiments. But do not beleive that I mean to tax your politeness by expecting you to read the whole of the Essay—You will of course consult your own convenience and feelings in relation to the subject but from your remarks I arrived at the conclusion that you were interested in researches in reference to Medicine and the Structure of the human system—I also send you a copy of a memorial on a subject concerning which I have learned that you are deeply interested the Geological Survey of the State—It has been sent on to our Delegates & presented to the Legislature. I trust that body will take measures to have such a survey made forthwith—I will not my dear Sir continue to trespass longer. I fear that I have already been intrusive in occupying this much of your time and attention but when I found from the visit at your house that you appeared interested in these subjects and your mind open to every kind of subject I felt emboldened to send the accompanying Documents—With my best respects to Mrs Madison and to Miss Paine—I am Sir with the greatest respect, Yr obt. servant.
