of a givon locality being precisely determined, and partly experi- 

 mental, an explanation of the causeg of the phenomena observed 

 being sought for by nieaus of cultures and laboratory examination. 

 The other two papers concerned the Fucacese of the Salt Marsh. 

 The first (Jourii. Linn. 8oc,, Bot. xl. 1912, pp. 275-291) gave an 

 account of certain Marsh Fucoids at Blakeney Point and else- 

 where ; and the second, in collaboration with Mi^ss M. H. Bohling 

 (Journ. Linn, fcjoc, Eot. xliii. 1916, pp. 325-380), was of very 

 wide scope, and formed the most important general contribution 

 to the subject 3'^et published. The authors give first an excellent 

 and critical systematic revision of the salt-marsh fucoids, for 

 which their ecological training especially fitted them ; secondly 

 a discussion, based largely on experimental work, of the relation 

 of the physical factors of the habitat to the peculiar morphology of 

 the various species which occur ; and lastly, a general account of 

 the distribution of tliese fucoids in connection with such problems 

 as pioneer vegetation and coast erosion. 



Of purely physiological work Miss Baker's most important 

 research — on water-entry and transport in ti'ees — is, though 

 fully written up, still unpublished. She also maintained an 

 interest in Silver Leaf, though latterly she held somewhat 

 ditterent views to those expressed in the note published in 1913, 

 in which the ingenious method of using the enzyme of Goprinus 

 spp. as a cure for this disease was described. 



Miss Baker was one of the principal and most enthusiastic 

 workers of the Blakeney Point Survey, where her persistence and 

 high sense of duty were admired by all. As a teacher she Avas 

 no less successful tha.u as an investigator, her lectures being marked 

 by extreme lucidity, as those who heard her two papers at the 

 Linnean Society will have gathered. Her contributions to science 

 were characterised by originality and thoroughness, and by her 

 sympathetic interest in all branches of botany as well as in social 

 and other problems, her loss v.ill be widely felt, but especially by 

 that school of Botany in London to which she was so warmly 

 attached and by which she was so fully valued and appreciated.

Alfred Celestin CoQKiArx, who died at Genappe on the 15th 

 A[)ril, 191(3, aged 75, was born at Kobechies, Haiuault, on the 

 7th April, 1841. After passing through a local school, in 1852 

 he became a pupil at the Normal School at Nivelles. In 1861 he 

 successfully passed the examination for a teacher, and the following 

 year received the diploma, and leaving Nivelles, spent a busy ten 

 years as teacher at various places, as Borinage and Pliilippeville, 

 in 1863 producing his first btitanic paper on Xitella travissima, in 

 the Bulletin de la Society Royale de Botanique de Belgique, where 

 many of his shorter papers, dealing with local botany, were printed. 

 The year 1872 witnessed his call as Conservator of the Brussels 

 Botanic Garden, remaining there till 1880, when he became Pro- 

 fessor of Natural History in Jodoigne for four years, when he
