problems of experimental parthenogenesis, until ihe lailure of his 

 eyesight compelled him to give up practical observations and 

 devote liimself to writing. Already in 1895 he wrote a monu- 

 mental volume on ' Les Theories de I'heredito et les grands pro- 

 blemes de Hiologie gcnerale,' and next year in collaboration with 

 Herouard began to publisli the Aaliiable aud beautifully illustrated 

 'Zoologie Concrete." Next he started the ' Annce Biologique,' a 

 very useful summary of current work on general zoology. Smaller 

 books on 'Les Theories de I'Evolution.' 1909, and on 'La 

 Parthenogenese,' 1913, were published in collaboration with 

 31. Goldsmith. Lastly, shortly before his death, appeared a 

 treatise on Dreams. He was elected a Toreign Member on the 

 6th May, 1909. • [E. S. G.] 



Henry John Moreton, 3rd Earl of Ducie, born 25th June, 1827, 

 was descended from Sir John Diicie, Lord Mayor of London and 

 Eanker to Charles 1. Educated at Eton, he was one of the last 

 survivors of the last "Montem " in 1844. He succeeded his father 

 in 1853, and for a period of 70 years played the i)art of a great 

 English landowner and an assiduous patron of science and art. 



A o-eolooist and botanist of some eminence, in virtue of which 

 he was elected a Eellow of the Eoyal Society in lb55. He was 

 liord Lieutenant of Gloucestershire for 54 years, and at the time 

 of his death he was "Eather " of the House of Lords, of the Privy 

 Council, of tlie Eoyal Society, of the Geological Society, and of 

 many other Societies and Institutions. 



Lord Ducie was a Eellow of the Linnean Society for upwards 

 of 32 years, and although he took no prominent part in its pro- 

 ceedings he devoted his long life to the scientific study of plants, 

 and especially to the study of trees, both couiferovis and broad- 

 leaved. He was also an ardent yachtsman and traveller, and at 

 Tortworth in Gloucestershire, from his earliest years onwards, he 

 amassed a large collection of trees from the temperate regions of 

 the world. Of these he kept a painstaking record, and though he 

 could never be induced to publish a catalogue, it may safely be 

 said that the collection is surpassed by very few in the country. 

 A leading authority on arboriculture, he was one of the first to 

 recoo-nise the value of the Douglas Eir (Pseudofsuga DongJasn), 

 and one of the earliest and most famous plantations of this great 

 timber tree may be seen at Tortworth. Some of the oldest speci- 

 mens, too, of the Japanese Larch {Lnriv lejAolepis) were planted 

 by him; of the Chilean Beach {NoOiofagus obliqva), which was 

 introduced to this country by his old friend, Henry Elwes,E.li.S., 

 and of the Oregon Chestnut {Casta nopsis chrysoplujlla) he possessed 

 perhaps the largest and oldest specimens in the country, not to 

 mention numerous other trees, Oaks and Hickories in particular, 

 with which he delighted to experiment with a view to eoonomic 

 or ornamental utility. 



Lord Ducie shared with the late Monsieur Allard, of Augers, the 

 rare satisfaction of being spared to see his plantations of broad-
