"But there were many substances which he not only touched, but smelled during his examination. "To the sense of smell he seemed chiefly indebted for his knowledge of different persons. He appeared to know his relations and intimate friends, by smelling them very slightly, and he at once detected strangers." From the whole of this interesting relation, it seems fair to conclude that this youth, even under the privation of sight and hearing, possessed, in the staple of his intellect, capacities beyond the most docile animals; and these consisted in the ardent curiosity which he displayed, and in his desire for the improvement of his limited faculties. Had this boy been confided to my management, I should have endeavoured to educate him through the medium of his touch, so as to communicate his wants, and afford an occupation to his mind. Thus, if milk had uniformly been served to him in a bowl, beer in a mug, water in a decanter with a glass stopper, and wine in a decanter with a cork: if these had been arranged in his apartment, he might have indicated his wish for any of these liquids, by producing the vessel that contained them: the two latter might have been subsequently abbreviated, by producing the glass stopper for water and the cork for wine. As he examined every object by the touch, it would have contributed both to his improvement and occupation, if he had been furnished with a quantity of ductile clay, which he might have modelled to represent the objects he examined, and which he might have preserved as a species of tangible vocabulary. According to my own suppositions, he might have been taught to numerate. It may be a subject of considerable curiosity to enquire, of what the reflections of James Mitchel could have consisted. He had no visible impressions which his hand could record. Being deaf, he could not have acquired the instrument of thought--language; therefore, for the objects of the senses he possessed,--smell, taste, and touch,--he could have no terms, as their substitutes, for the purpose of recollection. The next important question is, in what manner (wanting names whereby they might be represented) would the perceptions of smell, taste, and touch be represented to his mind in order to constitute reflection or thought on these experienced perceptions? If musk, rose, or garlic had been smelled, these perceptions, in a being constructed like Mitchel, would remain dormant, until the same odour were again presented to his olfactory organ; when it would be recollected, or he would be conscious, that it had been previously presented. In such a being, there would be a necessity for a fresh excitation of the organ of sense by the object, to produce recollection; whereas, in those who possess language, the name produces the recollection of the thing perceived.
