He \vas elected an Associate of the Society on the IGtli Decem- 

 ber, 1897, and died at Chatteris, 2Gth February, 1912, where he had 

 carried on the business of nurseryman. His pi'inted contributions 

 to Science, besides the unfinished monograph referred to above,, 

 consisted in papers to the 'Journal of Botany' for a series of 

 years, from 1883 onwards, on his special genus Potamoc/eton, and 

 bear witness to the careful and valuable results he evolved from 

 these studies. [Arthur Bennett.] 



Albert Harrison was born in 1860 at the JVew Pale Farm, 

 Frodsham, Cheshire, and received his education at the Liverpool 

 Institute, leaving at the age of 15 to enter the sugar refinery of 

 Henry Tate & Sons in Liverpool, and three years later was trans- 

 ferred to the London branch, where he obtained rapid promotion,. 

 and finally was made manager. 



The home of his boyhood being close to Delamere Forest, he 

 early imbibed a liking for Natural History, and he usually spent 

 part of his annual holiday in that forest. It was not till 1888' 

 that he took up the study of the Lepidoptera in a serious way. 

 Then he joined forces Avith his brother-in-law, Mr. Hugh Main, 

 and the two experimented on forms oi Aj^lecta nehulosd and Pieris 

 oiapi, and latterly on Boarmia repandata. Mendelian results 

 greatly interested him. He was a member of many biological 

 associations, and in 1899 was President of the Entomological 

 Society. He was elected Fellow of the Liunean Society 

 3rd November, 1898 ; he was also Fellow of the Zoological, 

 Eoyal Microscopical, and Chemical Societies. He died suddenly 

 of apoplexy at his house at South Woodford, on 28th August, 1911, 

 and was buried at Alvanley, in Cheshire. [B. D. J.] 



JosEPn Dalton Hooker. — By the death of ?ir Joseph Hooker 

 on Sunday, December 10th, 1911, in his 95th year, the Linnean 

 Society has lost at once the most renowned of all its Fellows and 

 one of the most remarkable men VAho ever devoted his life to the 

 advancement of Science. Hooker's ancestry and parentage do not 

 require to be set forth here in detail. The son of Sir William 

 Hooker, the Founder of Kew, he hailed from East Angiia — a part 

 of England which can hold its own with any other region in the 

 cumber and eminence of the Naturalists which it has cradled. 

 Had Hooker lived another six months it would have been exactly 

 70 years since he was elected into the Linnean Society (June 7th, 

 1842). Nor does this lapse of time represent the full working 

 life of this great man, for already on his election he had won 

 his spurs as a botanical traveller in the Antarctic. His life- 

 long friend, Asa Gray, in a letter written about this time to 

 Sir William Hooker, says * : —
