LINNEAN SOCIETY OF LONDON. 



April 3, 1890. — Mr. W. Carruthers, F.R.S., President, in the 

 chair. — Mr. John Low was admitted and Rev. J. Scott elected a 

 Fellow of the Society. — Mr. B. D. Jackson exhibited some seeds of 

 Mystacidium Jilicorme, an epiphytic Orchid forwarded from South 

 Africa by Mr. Henry Hutton, of Kimberley. 



April 17. — Mr. W. Carruthers, F.R.S., President, in the chair. 

 — Messrs. E. C. Galpin, J. Johnson, W. F. Kirby, J. B. Carruthers, 

 and J. S. Turner were elected Fellows of the Society. — Lord Arthur 

 Russell, on behalf of the subscribers to a portrait of Sir Joseph 

 Dalton Hooker, which had been painted at their request by Mr. 

 Hubert Herkomer, R.A., formally presented the portrait to the 

 Society, and in a few words expressed the satisfaction which he was 

 sure would be felt at the acquisition of the likeness of so dis- 

 tinguished a botanist. It was announced that a photogravure of the 

 portrait was in preparation, of which a copy would be presented when 

 ready to every subscriber to the portrait fund. — Dr. Edward Fischer, 

 of Zurich, exhibited and made remarks on certain species of Polyporus 

 bearing a sclerotium possessing the structure of Pachyma Cocos, but 

 it was doubtful whether the Polyporus represented the fructification 

 of the Pachyma, or was merely parasitic on it. Mr. George Murray 

 expressed himself in favour of the latter view. — A paper was then 

 read by Mr. Spencer Moore, " On some micro-chemical reactions of 

 Tannin." In this an account was given of the behaviour of 

 Nessler's test for ammonia upon tannin, which it usually colours 

 almost immediately some shade of brown or reddish brown. The 

 great value of the reagent is held to reside in the rapidity of its 

 action ; moreover, in none of the many experiments did it fail. 

 Reference was also made to some other new tannin tests, especially 

 to some in which, as in Nessler's fluid, caustic potash furnishes 

 the basis, and which, like that fluid, are very rapid in their action. 



We are glad to announce that our valued correspondent, Mr. 

 J. E. Bagnall, A.L.S., who has worked so long and so carefully at 

 Warwickshire Botany, has almost ready for the press a new ' Flora 

 of Warwickshire,' which will be issued with as little delay as 

 possible. The work will be limited to 500 copies, and will be 

 published at a subscription price of 12s. 6d. Subscribers' names 

 should be forwarded to the author, 84, Witton Road, Aston, Bir- 

 mingham.
