a very full account of that history, which he prefaces with Robert 

 Plot's (not " Plot£ ") account of " Meldews " (1686) and concludes 

 with a full list of the British species of the group. Miss Lister 

 also enumerates the Mycetozoa found during the " foray" in the 

 Forres district last September, with the description and plate of 

 a new T species, Lamproderma insessum : the other papers include 

 notes on the fungus-flora of the Moray district, by D. A. Boyd ; 

 notes on British species of Corticiwn, by E. M. Wakefield ; 

 descriptions of two new species (Ascobolus Carleioni and Calycella 

 Menziesii) by M. Emile Boudier, with a beautiful plate by Mr. 

 Carleton Rea ; and descriptions of new and rare British fungi by 

 the editor, Mr. Carleton Rea, Miss Lorrain Smith, Mr. J. W. Ellis, 

 Dr. Jessie Elliott, and Mr. Ramsbottom. The part, which con- 

 tains 198 pages, is issued by Messrs. Baylis & Son, of Worcester, 

 and is issued to non-members at the reasonable price of 10s. 6d. 

 It is w 7 ell printed, but we think the practice followed in this 

 Journal of printing the names of new species in conspicuous type 

 would add to the convenience of reference, and it seems a pity not 

 to utilize the headings of the pages for giving information as to 

 the matter to be found beneath. 



At the meeting of the Linnean Society on May 1, a paper by 

 Prof. Percy Groom, F.L.S., and Mr. W. Rushton, entitled "The 

 Structure of the Wood of East Indian species of Pinus," was 

 explained by Prof. Groom. The paper contained an account of 

 the structure of the secondary wood of the five Indian species 

 of Pimis. The following points of more general interest were 

 mentioned. In P. Khasya and P. Merkusii there occur radial 

 bundles of bent tracheides having bordered pits on all their walls. 

 In P. Merkusii the pits on the radial walls of the normal spring- 

 tracheids are often triseriate but typically abietinean in form and 

 arrangement ; but often they are grouped together in " nests " of 

 three or four, forming patterns like those in the fossil Cedroxylon 

 transiens W. Gothan, which, in addition, showed typical araucarian 

 pitting. According to Sanio, one or more bordered pits arise in a 

 " primordial pit-area," and frequently do not occupy the whole 

 area; the authors, relying on Sanio, point out that the band-like 

 markings fringing individual pits in uniserate type, or pairs, or 

 threes, or groups of pits in the other species of Pinus, represent 

 the persistent margins of the original primordial pit-area : hence 

 they term these bands " Sanio's rims." Where a Sanio's rim 

 occurs the structure of the wall is peculiar ; the middle lamella is 

 pectic and not perceptibly lignified ; the remaining part of the 

 wall is lignified. Elsewhere the middle lamella does not stain so 

 deeply or typically with pectin reagents, but does stain with 

 phloroglucin and hydrochloric acid. These " Sanio's rims " are 

 the structures termed by Miss Gerry " Sanio's bars," and are in 

 no way composed of cellulose, as she alleges. The term " Sanio's 

 bars " was invented by G. Muller, and he defined them as rod-like 

 structures crossing the lumina of tracheides or constituents of the 

 phloem, which are lignified in the xylem but not so in the phloem. 

 C. Muller made the generalisation that "Sanio's bars" occur in
