ON THE SENSE OF TOUCH, PHYSIOLOGY AND PHILOSOPHY OPPOSED TO MATERIALISM AND ATHEISM BEING AN INTRODUCTORY DISCOURSE, DELIVERED ON THE 6TH DAY OF NOVEMBER, 1837, ON THE OPENING OF THE NEW COLLEGE, IN CROSBY STREET. BY J. AUGUSTINE SMITH, M. D. MEMBER OF THE ROYAL COLLEGE OF SURGEONS OF LONDON, PRESIDENT OF THE COL- LEGE OF PHYSICIANS AND SURGEONS IN THE UNIVERSITY OF THE STATE OF NEW YORK, AND PROFESSOR OF PHYSIOLOGY IN THAT INSTITUTION. NEW YORK : W. E. DEAN PRINTER & PUBLISHER, 2 ANN STREET. 1837. - fJW Entered, According to the Act of Congress, in the year 1837, by W. E. DEAN, In the Clerk's Office of the Southern District of New Yore, TO THE REV. REUEL KEITH, D. D. PROFESSOR OF SYSTEMATIC THEOLOGY, &C, IN THE PROTESTANT EPISCOPAL SEMINARY IN THE DIOCESS OF VIRGINIA. Dear Sir : You have on more than one occasion expressed a wish to see the argument which I informed you I had devised against the Atheists. It is accordingly now submitted to your consideration. But what you and others, who appreciate ab- stract discussions as they merit, will think of my logic, I can not anticipate. To me it appears novel, and I should add conclusive, had not such eminent philosophers failed in the attempt, which I have essayed. Yet whether demon- strative or not, an original train of thought tending to estab- lish the existence of the Deity, is not without its value. The reasoning therefore which I have employed in support of the sublimest of all truths, if less forcible than parental fondness would represent it, may, nevertheless, be esteem- ed a contribution on my part from Science to Religion. As a prelude to the remarks in opposition to the Atheists, and for reasons stated in the Lecture, I have thought it well to pass Materialism through the metaphysical cruci- ble. Of my analysis and its results I need not speak, since you are an equally competent and more impartial judge, than yours, With continued Friendship and esteem, J. AUG. SMITH. New Yore:, 7th Nov. 1837. ON THE SENSE OF TOUCH Gentlemen, I am happy to announce that through the fostering care of the Regents, and the judicious kindness of the Trustees, our College opens for the ensuing Session under the most favourable auspices. We have exchanged our former con- fined and inconvenient apartments, for the spacious and most commodious building in which we are now convened. But what is of far greater consequence, we have no small accession of new talent,* and there has consequently been infused into the Faculty an augmented power of imparting knowledge. Under these fortunate circumstances it be- comes my pleasing duty as presiding officer of the institu- tion, to deliver an address in some measure commensurate with the importance of the occasion. Accordingly I have selected topics of the deepest interest to responsible be- ings, which a physiologist, who is also a layman, is permit- ted to treat. For although the Sense of Touch is my theme, yet in discussing it, I hope to prove that man differs some- * Dr. Alban G. Smith and Dr. Auiariah Brigham have been appointed to chairs in the College during the vacation ; the former to teach Sur- gery, the latter Special Anatomy. SENSE OF TOUCH. what from the dust on which he treads, and that the vast fabric of the universe is the work of Omnipotence. But to establish these truths the ordinary limits* of a lecture will not suffice. A tax therefore will have to be imposed, though most unwillingly, upon your patience ; yet those whose good nature may induce them to bear with some excess, will, I flatter myself, be rewarded by an occasional sugges- tion, both novel and gratifying. Where my ideas are more trite, the dignity of my subject must stand for their apology. Of the five inlets to knowledge not one is more widely disseminated than the Sense of Touch. Belonging indeed, to the minutest microscopic insects as it is seen to do, (a) it is probably co-extensive with animal life, (b) But as the tactile power is most exquisite in the fifth, and as that is also the gustatory nerve, to feel and to taste, are, perhaps in all creatures, associate faculties. In man a capacity to perceive the tangible qualities of matter is diffused in some degree over his whole body, but it resides more particularly in the tip of the tongue, and the ends of the fingers, and toes. In the first and the last it is seldom called into use, except in cases of deformity or disease. Where the hands have been wanting, the toes have to a certain extent become substitutes for the fingers ; and two casesf have been re- ported to me, on authority not to be doubted, in which blind persons were enabled to thread needles by the aid of their tongues.J But it is the papillae at the ends of the fingers * Hence, the number and the length of the notes, into which every thing has been thrown that could be dispensed with in the text. t This feat, however, requires I suspect many efforts before it can be accomplished ; at any rate I have attempted it in vain. t One of these is the celebrated Julia Brace of Hartford, who is deaf, dumb, and blind ; the other was a member of one of the first families in our country.
