opened out or planted during his ee ae especially in the 
Arboretum, To mention only a few of these, the Thorn avenue 
was planted in 1868, that of Atlas Cedars was fate in 1871, the 
Holly walk in 1874, ‘the Sweet Chestnut avenue in 1880. A new 
system of supplying water was established between 1866 and 1868; 
the stables were removed to a more suitable site in 1867 and their 
removal enabled the opening of the present Cumberland Gate. 
The d vine and entrance known as the Isleworth Gate was 
provided in 
The range ae plant-houses known as the T-range was erected in 
1868-9; the Jodrell Laboratory was added to the institution in 
1876 ; a new hall, added to the Herbarium building, was completed 
in 187 7; a wing was added to No. I. Museum in 1881, and the North 
Gallery was completed and opened to the public in 1882. 
With all the burden of these duties upon him Hooker was still 
able to take his full share of the public work that falls to be per 
formed by men of science. In 1866 he undertook to deliver one: of 
8, 
alluded to. oe 1868 he was President of the meeting of the 
fs aa held at Norwich, and his opening aides mich seal 
the value and functions of museums, was pre y a 
anquaified advocacy of the acceptance of the by poles of his 
friend Darwin as the surest means of promoting natural knowledge, 
which produced a marked and lasting effect on scientific thought. 
In 1874 he was chairman of the department of Zoology and Botany 
in the Biological section at the meeting of the Association in 
Belfast, taking as nis subject the carnivorous habits of plants and 
reviewing a group of problems to which his own observations and 
researches on Nepenthes, published in 1859, had drawn especial 
attention. In 1881 he Dresided over the Geographical section of 
the Association at its meeting in York and delivered an address on 
‘Geographical Distribution’ of the greatest importance and value. 
In 1873 Hooker was chosen to fill the highest post to which an 
English man of science can attain—the -Presidentship of the 
pss aa b ; he occupied the presidential chair during the next 
five years. As our record indicates, the exacting duties which this 
Salivion entails neither interfered with the performance of his 
administrative work nor curtailed his activity as a botanical author. 
To this activity we again turn in order to record the commencement 
of what was to prove in some respects the heaviest and most sus- 
tained of the tasks of his life. The beara ion of the Indian 
specimens on which Hooker and Thomson had been engaged was 
hardly completed when a similar Seceanity arose through the 
accession of the Peninsular Indian herbarium of Dr. Wight. The 
catalogue required for this collection was ready for issue and the 
preliminary work completed by 1870. The preparation of a ‘ Flora 
of British India’ on the lines of the Colonial Floras prepared at 
Kew could at last be begun. The opening part of the first volume 
was issued in 1872 and the volume completed in 1875. The second 
volume was completed in 1879, the third in 1882, and the fourth in 
August, 1885. Three months later Hooker retired from the 
Ductoesbis of Kew, taking up his residence at the Camp, near
