At this date, however, an event of great interest occurred in connection with the agitation of the slavery question,--an event exercising a most decided influence on the career of Dr. Bailey,--in fact, changing entirely the current of his eventful life. We allude to the discussions of slavery at Lane Seminary, and the memorable expulsion of a number of the students for their persistence in promulging antislavery doctrines. Dr. Bailey was then engaged at the Seminary in the delivery of a course of lectures on Physiology. He became interested in the pending discussion, and espoused the proslavery side. For this his mind had probably been unconsciously prepared by the current of thought in Cincinnati, then under the mercantile control of her proslavery customers from Kentucky and other Southern States. But erelong he appeared as a convert to the antislavery side of the discussion. This he himself was wont to attribute, in great part, to the light which an honest comparison of views threw upon the subject; but it is evident that his conversion was somewhat accelerated by the expulsion of his antislavery antagonists in debate. Following the lead of these new sympathies, he became (in 1835) editorially associated with that great pioneer advocate of freedom, James G. Birney, whose venerated name has been so honorably connected with the recent triumph of the Union arms, through the courage of three of his sons. The paper was "The Cincinnati Philanthropist," so well remembered by the earlier espousers of antislavery truth. The association continued about a year. Dr. Bailey then became sole editor of the Philanthropist, and soon after sole proprietor. It was from the pages of this journal that a series of antislavery tracts were reprinted, which had not a little to do in giving fresh impulse to the discussions of that day. They were entitled "Facts for the People."
