After leaving Audubon at Henderson in the summer of 1818, Rafinesque passed down the Ohio into the Mississippi, pausing only to pay his respects at the famous communistic settlement of New Harmony, by the mouth of the Wabash in Indiana, then the abode of Thomas Say, David Dale Owen, and Charles Le Sueur, all of whom have left bright and honored names in the annals of American science. He eventually returned to Philadelphia by way of Lexington, Kentucky, where he was induced to settle and teach natural history and the modern languages in the Transylvania University, at that time the most important seat of learning in the West. After closing up his business affairs in Philadelphia, Rafinesque entered upon his new labors at Lexington in the autumn of 1819. He was probably the first teacher of these subjects west of the Alleghanies, and certainly the first in that section of the country to use the present object method in the elucidation of natural history. The lot of a pioneer in education has never been a sinecure, and the post which Rafinesque then filled was not a "chair" but a hard "settee." In those days the classics were in the saddle and "rode mankind," while the natural sciences, when tolerated at all, were given short shrift; yet this eccentric foreigner held his position for seven years and accomplished an extraordinary amount of work. As usual he spread his energies over the whole field of knowledge, lecturing, writing and publishing on almost every subject, but concentrating upon none. Meanwhile, he roamed far and wide and made extensive collections. While at the Transylvania University Rafinesque seems to have applied for the master of arts' degree, but was at first refused, as he said, "because I had not studied Greek in a college, although I knew more languages than all of the American colleges united, but it was granted at last; but the Doctor of medicine was not granted, because I would not superintend anatomical dissections."
