 Rh achievements over the whole of his professional career, including the Glasgow period together with his later years at Kew.

Taking first the living collections, he had already shown at Glasgow, where the opportunities were more limited than at Kew, a singular success in securing additions to the plants under cultivation. This is now reflected more clearly in the lists which were published from time to time than in any actual specimens still living after the vicissitudes of cultivation of 70 years; though it is not improbable that some of our older specimens date from his period of office. The current floristic serials, many of them produced and even personally illustrated by himself, also form a record of the novelties from time to time secured. This rapid growth of the Glasgow garden has already been noted, and the large number of the plants introduced under his influence. It only required the same methods to be put in practice in the larger sphere of action of the metropolis to ensure a similar, though a far greater result at Kew. Moreover, the official position which he there held as Director, gave an increasing obligation to meet his wishes on the part of foreign and colonial gardens, and other sources of supply. Notable among the many other living collections that resulted was the series of Ferns, already a subject of his detailed study while at Glasgow. In its maintenance and increase he was ably assisted by the Curator, Mr John Smith, himself no small a contributor to the systematic treatment of the Ferns. Hooker's aim was, however, not to forward the interests of any special group of plants, but to make the collections as representative as possible. This is clearly reflected in the various character of the plant-houses successively built at his instigation, and remaining still to testify to the catholicity of his views.

In the days at Glasgow, Sir William had already made his private museum ancillary to the living collections, in his endeavour to demonstrate the characters of the vegetable world. This line of demonstration he further developed after his removal to Kew, and the results, together with later additions, but with methods little changed, are to be seen in the splendid museums of the Gardens at the present time. The specimens were from the first mainly illustrative of Economic Botany, such as are of
