QUEKETT MICROSCOPICAL CLUB. 207 



cigarette paper, and also tlie Japanese hand-made papers, are 

 probably made from high-grade cotton. When old paper is used 

 for making new paper it is necessary to add fresh material in order 

 to stifien it. Mechanical wood-pulp paper goes brown, and falls 

 to pieces very quickly. Wood-pulp and cotton-fibre paper lasts 

 well, but for real lasting qualities that made of linen and cotton 

 fibre is the best. Jute would last, but the colour is bad. The best 

 paper is made from white rags, as less bleaching is necessary. 

 The melting together of the fibres in grease-proof papers is done 

 b>y chemical means ; prolonged heating would not have the 

 same effect. 



A very hearty vote of thanks was accorded to Mr. Wycherley 

 for his interesting paper. 



At the 553rd Ordinary Meeting of the Club, held on June 8th, 

 the President, Dr. A. B. Rendle, M.A., F.R.S., in the chair, the 

 minutes of the meeting held on May 11th were read and confirmed. 



Miss Blanche Dell, Messrs. Lionel B. Ridley, C. E. Raison, A. W. 

 Richardson and Alfred W. Stokes were balloted for and duly 

 -elected members of the Club. Five nominations were read for the 

 first time. 



The Assistant Hon. Secretary announced that the next Ordinary 

 Meeting would be held on September 14th, Conversational Meet- 

 ings being held as usual on the second and fourth Tuesdays of 

 «ach month until that date. 



A valuable paper by Mr. G. T. Harris on " The Desmid Flora 

 of a Triassic District " was taken as read. The Assistant Hon. 

 Secretary read the following paragraph from the paper, which 

 gives some idea of its scope : 



" The comparative table given of the desmid floras of the two 

 districts (Dartmoor and East Devon), one a Palaeozoic semi-moun- 

 tainous area of extensive peat deposits, excessive rainfall and 

 deep bogs, the other a Triassic lowland area with no peat deposits, 

 moderate rainfall and bogs unimportant both in depth and 

 extent, would indicate that the factors influencing the richness or 

 poverty of desmid floras must be sought for elsewhere than in the 

 geological beds upon which the habitats stand, and a recent 

 investigation of the desmid flora of a district on Eocene beds con- 

 firms this statement."
