190 LINNEAN SOCIETY OP LONDON. 



highly differentiated, condition, and showed that, so far as known, 

 the histological structure and development were essentially the 

 same throughout the order. Various special forms, such as the 

 needles of Finns, the phylloid shoots of Sciadopitys, and the seed- 

 scales of AhietinecB, were described, and their significance pointed 

 out. The phenomenon of enation, with the correlative inversion 

 of the fibro- vascular bundles in such outgrowth, was considered in 

 relation to the lights it throws upon certain contested points in the 

 morphology of the order. The chief teratological appearances 

 noted in the order were detailed, and the significance discussed. 

 The various modifications were shown to be purely hereditary or 

 partly adaptive, and dependent on permanent or independent 

 arrest, excess, or perversion of growth and development, and to 

 various correlative changes. Lastly, the polymorphic forms of the 

 so-called genus Retinospora suggested that in studying them we 

 might be watching the development and fixation of new specific 

 types. 



May 2.— Mr. C. B. Clarke, M.A., F.K.S., in the chair.— 

 Messrs. H. B. Hewetson (of Leeds), M. B. Slater, and T. W. 

 Shore were admitted Fellows of the Societies ; and Messrs. C. 

 Hedley, T. W. Girdlestone, and E. E. Prince were elected. 

 Prof. W. Pfeffer, of the University of Tubingen, was elected a 

 Foreign Member. — With reference to a recent exhibition by Mr. D. 

 Morris, of leaves of different species or varieties of plants included 

 under Erythroxylori Coca Lamarck, Mr. Thomas Christy made 

 some remarks on the leaves of a variety from Japan. These he 

 described as brittle and thin, with hardly any trace of cocaine, 

 though yielding 8 per cent, of crystallizable substance. The 

 thicker leaves of the Peruvian plant yielded more cocaine, though 

 at first rejected on account of their more glutinous nature — Mr. 

 John Carruthers read a short paper " On the cystocarps, hitherto un- 

 described, of a well-known seaweed, Rhodymenia palmata." — The 

 second part of a monograph of the Thelejohorem was communicated 

 by Mr. G. Massee. — Mr. Mitten contributed a paper " On all the 

 known species of Musci and Hepatica recorded from Japan." An 

 interesting discussion followed, on the character of the Japanese 

 Flora. 



May 24, 1889. — Amiiversary Meeting. — Mr. Carruthers, F.E.S., 

 President, in the chair. — The following were admitted as Fellows : 

 The Rt. Hon. the Earl of Ducie, P.C., F.R.S., Messrs. W. J. 

 Hindmarsh, C. M. Peal, R. W. Scully, T. W. Girdlestone, and 

 William Kirkby. — A portrait of John Jacob Dillenius (1687-1747), 

 the first Professor of Botany at Oxford, copied from the original 

 picture at Oxford, was presented to the Society by the President, who 

 gave a brief outline of his career and of his personal acquaintance 

 with Linnaeus. — The Treasurer having made his annual statement 

 of accounts, and the Librarian's and other Reports having been 

 read, a ballot took place for the election of Officers and Council for 

 the ensuing year. The President, Treasurer, and Secretaries were 

 re-elected, and the changes recommended in the Council were
