Excerpt from The American Monthly Magazine and Critical Review, 1818, Vol. 3 That such ardent and constant intel lectual exertions were not calculated te do good to his constitution, will not ex cite surprise; and the anxiety of his re latives became awakened at the symp toms of disease which he himself little regained. In order to restore him to his former health, he was persuaded to aban don for a time his closet studies. It has often been observed, that a change of mental occupation is itself suficient for the purposes of physical renovation. He now resolved to indulge that fondness for the works of nature, to which, at an early age, he had formed an attachment, but which he had, from various circumstances, been prevented from gratifying. That his attainments in this pleasing depart ment of rational investigation, entitled him to high praise, cannot be denied; and the success that attended his labours in botany and mineralogy, is known to the cultivators ofthese branches of science.
