182 The Life and Work of John Ray, and seem to have hindered his work; for his unceasing industry and marvellous productiveness are not the least proofs of the genius of this great man. Not till 1682 have we any other work from his pen; but to that year belongs the first edition of the 'Methodus Plantarum nova,' one of the corner-stones of his philosophical fame. It was an expansion of the tables he had drawn up for Dr. Wilkins in 1668 ; and in it he describes the true nature of buds, speaking of them as annual plants, springing from the old stock; and recognises the important division of flowering plants into Dicotyledones and Monocotyledones, and many of the natural orders, such as Umbelliferae, Stellate, Boraginaceae, Labiate, Pomaceae, Cruciferae, Leguminosae, Palmaceae, and Coniferae, of which we now make use. Above all, basing his system largely upon the fruit, but also in part now upon the flower and now upon the leaf, he made the first thorough step towards the establishment of a natural system of classification ; and his arrangement (which was too far in advance of his time to be much appreciated, and was soon temporarily overlooked by the enthusiastic followers of tho artificial system of Linnaeus), in the words of Dr. Lindley, "when altered and amended, as it subsequently was by himself at a later period, unquestionably formed the basis of that method which under the name of the system of Jussieu is universally received at the present day." From a too conservative spirit of caution he at this time retained the old division into trees, herbs, and shrubs, and made the unfortunate mistake of denying the existence of buds on herbaceous plants; but while in the second edition, in 1703, he reduced these divisions into the two of woody and herbaceous plants, he only retained these out of deference to established usage. He acknowledges his indebtedness to Caesalpinus, who preceded him by a century, and whom he styles the "parent of system"; but, if Caesalpinus was the Wiclif of this Reformation, Ray was its Luther. In 1685 he was able, mainly by the help of his friend Mr. Dent, to issue a small appendix to his Cambridge Catalogue; but the death in 1683 of his fellow-student of system, Robert
