His first visit to this country was in 1802. He remained until 1804, when he went to Sicily, where he commenced business. As the French were unpopular there, he added "Schmaltz" to his name, for "prudent considerations," that being the surname of his mother's family.

In 1815 he returned to America, but had the misfortune to be shipwrecked on the coast, losing his manuscripts and much of his property. On his arrival, he supported himself by teaching, occupying his leisure time in scientific pursuits and travel. In 1819 he was appointed "Professor of Historical and Natural Sciences," in Transylvania University, Kentucky. This position he was obliged to resign, for technical reasons, in 1826, when he returned to Philadelphia, which city he made his home during the rest of his life.

From his early youth he was an indefatigable student, collector and writer in various branches of knowledge, especially in natural history. On the title-page of the last work that he published, "The Good Book and Amenities of Nature" (Philadelphia, 1840), he claims to be the author of "220 books, pamphlets, essays and tracts." Including his contributions to periodicals, there is no reason to doubt the correctness of this estimate. They began when he was nineteen, and were composed in English, French, Italian and Latin, all of which he wrote with facility.

His earlier essays were principally on botanical subjects; later, he included zoölogy and conchology; and during the last fifteen years of his life the history and antiquities of America appear to have occupied his most earnest attention.

The value of his writings in these various branches has been canvassed by several eminent critics in their respective lines.

First in point of time was Prof. Asa Gray, who in the year following Rafinesque's death published in the "American Journal of Science and Arts," Vol. XI, an analysis of his botanical writings. He awards him considerable credit for his earlier investigations, but much less for his later ones. To quote Dr. Gray's words: "A gradual deterioration will be observed in Rafinesque's botanical writings from 1819 to 1830, when the passion for establishing new genera and species appears to have become a complete monomania."[246] But modern believers in the doctrine of the evolution of plant forms and the development of botanical species will incline to think that there was a method in this madness, when they read the passage from Rafinesque's writings, about 1836, which Dr. Gray quotes as conclusively proving that, in things botanical, Rafinesque had lost his wits. It is this: "But it is needless to dispute about new genera, species and varieties. Every variety is a deviation, which becomes a species as soon as it is permanent by reproduction. Deviations in essential organs may thus gradually become new genera." This is really an anticipation of Darwinianism in botany.

The next year, in the same journal, appeared a "Notice of the Zoölogical Writings of the late C. S. Rafinesque," by Prof. S. S. Haldeman. It is, on the whole, depreciatory, and convicts Rafinesque of errors of observation as well as of inference; at the same time, not denying his enthusiasm and his occasional quickness to appreciate zoölogical facts.

In 1864 the conchological writings of Rafinesque were collected and published, in Philadelphia, by A. G. Binney and Geo. W. Tryon, Jr., without comments. One of the editors informs me that they have positive merit, although the author was too credulous and too desirous of novelties.

The antiquarian productions of Rafinesque, which interest us most in this connection, were reviewed with caustic severity by Dr. S. F. Haven,[247] especially the "Ancient Annals of Kentucky", which was printed as an introduction to Marshall's History of that State, in 1824. It is, indeed, an absurd production, a reconstruction of alleged history on the flimsiest foundations; but, alas! not a whit more absurd than the laborious card houses of many a subsequent antiquary of renown.

His principal work in this branch appeared in Philadelphia in 1836, entitled: "The American Nations; or, Outlines of a National History; of the Ancient and Modern Nations of North and South America." It was printed for the author, and is in two parts. Others were announced but never appeared, nor did the maps and illustrations which the title page promised. Its pages are filled with extravagant theories and baseless analogies. In the first part he prints with notes his translation of the The Walam Olum, and his explanation of its significance.
