SIR JOSEPH DALTON HOOKER—PRAIN. 665 
Hooker's succession in that year to the directorship of Kew brought 
with it all the responsibilities connected with the administration of 
that national institution. These, however, did not prevent him from 
continuing to take his share in the preparation of the Genera Plan- 
tarum, the second volume of which was completed in 1876, the third 
and concluding one in 1883. The directorship, however, brought 
with it the duties of continuing the Botanical Magazine and the 
Icones Plantarum, edited by his predecessor. These duties Hooker 
continued to fulfill even after his retirement in 1885; in the case of 
the Icones until 1889, in that of the Magazine until 1902, and with 
the collaboration of Mr. W. B. Hemsley for two years longer, his con- 
nection with this historic serial ending in 1904, with the completion 
of the one hundred and thirtieth volume. The death of his father 
imposed on Hooker yet another filial duty of the most arduous char- 
acter, that of replacing in 1870, by his own Student’s Flora, the 
British Flora of his predecessor. In 1873 he annotated and rear- 
ranged the natural families of plants in an English version of the 
Traité général of Le Maout and Decaisne, and in 1876 he wrote for 
the series of science primers that on Botany. 
The results of Hooker’s journeys in North Africa in 1871 are given 
in A Journal of a Tour in Marocco and the Great Atlas, written in 
collaboration with Ball and published in 1873; those of his visit to 
North America in 1877 were summarized by himself in Nature, vol. 
16, p. 539. 
Of the addresses and discourses delivered by Hooker during this 
period, that on Insular Floras of 1866 has already been alluded to. 
That delivered from the president’s chair to the British Association 
in 1868, with its whole-hearted advocacy of an acceptance of the 
hypothesis of Mr. Darwin as the surest means of promoting natural 
knowledge, was perhaps more important in its effect on scientific 
thought generally. His British Association sectional address of 1874, 
on The Carnivorous Habits of Plants, was an illuminating review of 
those problems to which his own observations and researches on 
Nepenthes in 1859 had directed attention. 
It has recently been remarked that ‘so broad-based were the foun- 
dations of Kew as laid by Sir William Hooker that they have been 
but little extended by his followers. Their work has been to build a 
noble superstructure. Viewed in detail, Kew is hardly anywhere 
the same as it was in 1865. But the framework is very much the 
same.” These remarks are so just that no useful purpose could be 
served by any attempt to enumerate here the various manifestations 
of Hooker’s activity as an administrator, or to detail the alterations 
and additions which marked his directorship. That activity, as was 
said by Prof. Asa Gray in the article on Hooker in our Scientific 
Worthies series (Nature, vol. 16, p. 538), was exercised ‘‘in such
