And with the many "bones choses" of the work of Rondelet, men were too long satisfied, and it was not until the impulse of commerce had brought them face to face with new series of animals not found in the Mediterranean that the work of investigating fishes was again resumed. About 1640, Prince Moritz (Maurice) of Nassau (1604-79) visited Brazil, taking with him two physicians, Georg Marcgraf (1610-44) and Wilhelm Piso. In the great work "Historia Naturalis Brasiliæ," published at Leyden (1648), Marcgraf described about one hundred species, all new to science, under Portuguese names and with a good deal of spirit and accuracy. This work was printed by Piso after Marcgraf's death, and his colored drawings--long afterward used by Bloch--are in the "History of Brazil" reduced to small and crude woodcuts. This is the first study of a local fish fauna outside the Mediterranean region and it reflects great credit on Marcgraf and on the illustrious prince whose assistant he was. There were no other similar attempts of importance in ichthyology for a hundred years, when Per Osbeck, an enthusiastic student of Linnæus, published (1757) the records of his cruise to China, under the name of "Iter Chinensis." At about the same time another of Linnæus' students, Fredrik Hasselquist, published, in his "Iter Palestinum" the account of his discoveries of fishes in Palestine and Egypt. More pretentious than these and of much value as an early record is Mark Catesby's (1679-1749) "Natural History of Carolina and the Bahamas," published in 1749, with large colored plates which are fairly correct except in those cases in which the drawing was made from memory. At about the same time, Hans Sloane (1660-1752) published his large volume on the "Fishes of Jamaica," Patrick Browne (1720-90) wrote on the fishes of the same region, while Father Charles Plumier (1646-1704) made paintings of the fishes of Martinique, long after used by Bloch and Lacépède. Dr. Alexander Garden (1730-91), of Charleston, S. C., collected fishes for Linnæus, as did also Dr. Pehr Kalm in his travels in the northern parts of the American colonies. With the revival of interest in general anatomy several naturalists took up the structure of fishes. Among these Günther mentions Borelli, Malpighi, Swammerdam, and Duverney. Other anatomists of later dates were Albrecht von Heller (1708-77), Peter Camper (1722-89), Felix Vicq d'Azyr (1748-94), and Alexander Monro (1783).
