Growth of the Sciences. 87 now comparatively free from the ignis fatwus of alchemy, and aided by the growth of institutions especially de- voted to its service, anticipated the course prescribed by the Baconian philosophy. Fracastorius (1483-1553) had, before the middle of the century, made an alliance between his art and literature ; later, VESALIUS (1514- 1564), the first great dissector, was followed by Ambrose Par4 Eustaehius, and Fallopius. In the kindred de- partment of botany, Duval, Bnmfels, Bock, Leonard Fuchs, and Luca Ghini (custodian at Pisa of the first Botanical garden) led up to Cesalpinus and Bauhin; while Conrad Gesner (1561-1565) laid the foundations of modern zoology. Mathematics were represented by Maurolycns, the first geometrician and optician of Iris age; and Vieta, successor of Cardan and predecessor of Harriot, the foremost algebraist. In physics, J. B. Benedetti was the earliest to recognise the tendency of propelled bodies to move in straight lines, and to analyse the composition of forces; while Simon Stevinus of Bruges, as early as 1585, by giving the first correct theory of the inclined plane, and of the vertical pressure of fluids, opened a new era in statics and hydrostatics. But the most important discoveries of tho age were made by a cluster of astronomers,1 who, living almost in the samo generation, seemed by destiny, if not design, to draw out each other's qualities and to supplement 1 Of the romantic careers of those groat men, who arc, with Coper- nicus, tho lathers of modern astronomy, it is only possible here to note that the fact of their all being more or less victims to the pre- judices of their age is, in some moaHure, an excuse for the habitually cautious attitude maintained, despite, his parade of defiance, by Francis Bacon, who had certainly no wish to be included with them in any future volume on "The Martyrs of Science."
