great zeal for the remainder of his life. His researches on these subjects, are among the most ingenious, if not the most useful of his labours. They enriched his philosophical inquiries and speculations with curious facts, and enhanced the value of his investigations of the materia medica and alimentaria, with some of their most important additions.
Dr. Rittenhouse, who early perceived and acknowledged the talents of his young relative, procured for him this important situation—important, as it gave the first impulse to that spirit of inquiry and research into the history of our Indians, which has resulted in an accumulation of so many curious materials relative to their origin and the affinities of their language.
This learned man continued to Dr. Barton, through life, a firm and a constant, as he was an illustrious friend. In a letter published in the memoirs of Rittenhouse, the doctor thus acknowledges the succour and the patronage he received from his distinguished relation:
