HISTORICAL ACCOUNT OF THE HERBARIUM. 55 
friendship that existed between the Rev. James Dalton and (Sir) 
William Jackson Hooker from 1805-1842. 
Sir William Jackson Hooker was born at Norwich in 1785. 
He was educated at Norwich, and early in life he took up the 
study of natural history as a recreation. 
In 1815 he married the eldest daughter of Mr. Dawson Turner, 
F.R.S., and whilst on his wedding tour he visited Mr. Dalton 
at Croft. 
In 1816 he issued his initial work on “ British Jungermanni^;,” 
a copy of which is in the library, and to-day this book occupies a 
foremost position in the literature on the subject. 
In 1818 another standard work was issued, “ Muscologia 
Britannica,"’ a copy of which is in the herbarium, and bears 
evidence of the friendship of these two botanists, as follows :— 
“ To the Rev. James Dalton , M.A., Rector of Croft , in Yorkshire. 
The following sheets are offered as a testimony of the most affectionate 
regard and esteem by W. J. Hooker and Thomas Taylor .” 
In 1820 he accepted the Regius Professorship of Botany in 
Glasgow University, where he remained 20 years, and it may be 
remarked that in 1824 he was elected honorary member of the 
Yorkshire Philosophical Society. 
For his distinguished services to science he received the honour 
of knighthood from William IV. in 1836, and later (1841) he was 
appointed Director of the Royal Botanical Gardens, Kew. He 
induced the Government to attach naturalists to all the important 
expeditions, and by these means he enlarged the herbarium at 
Kew and increased our knowledge of the vegetable products of the 
globe. The Kew gardens were opened to the public in 1841, and 
since then have been the admiration of all botanists. 
He died in 1865, and was succeeded at Kew by his son. 
(Sir) Joseph Dalton Hooker. This eminent botanist was 
born in 1817 (at Halesworth, Suffolk), and received his education 
at Glasgow. He derives the name of Dalton from his godfather, 
Rev. James Dalton. After taking his degree (M.D.), he received 
(in 1839) a commission as Assistant Surgeon on the Erebus under 
Captain (afterwards Sir) James Clark Ross, the leader of the 
Antarctic Expedition, 1839-1843. 
This expedition was the commencement of Sir J. D. Hooker’s 
remarkable botanical researches in the Flora of New Zealand,
