Prof. GrenvieeE A. J. CoeE showed a section of Chert from the 

 Aptian sandstone (Hythe Beds) of Leith Hill, Surrey. The chalcedonic 

 silica has collected round the quartz-grains of the sand, firmly cementing 

 them, and includes also numerous grains of glauconite. The chief 

 interest, however, centres in the abundant glauconitic casts of the 

 tubules of hexactinellid and tetractinellid sponge-spicules, which have 

 been left behind as evidence of the spicular origin of the silica which now 

 exists in the form of chert. In some cases the original spicule remains 

 round about the internal cast. The casts are often larger in cross-section 

 than the normal tubules of sponge-spicules, owing to the enlargement of 

 the tubules by solution prior to the infiltration of the glauconite. 



Mr. DuERDEN exhibited Plumularia similis, Hincks, a rather rare 

 hydroid obtained from shore-collections made between Laytown and the 

 mouth of the River Boyne, on the occasion of the recent visit of the 

 Dublin Naturalists' Field Club. It has only previously been recorded in 

 Ireland from Dublin Bay and Donaghadee.

A New Irish Bramble. — In the Journal of Botany for July Rev. E. 

 F. Linton publishes, under the name of Rubus Rogersii, a description of a 

 bramble allied to A', plicatus, opacus, nitidus, and ajfinis, which he considers 

 distinct, and names in honour of Rev. W. Moyle Rogers, who has done 

 so much to aid the study of British brambles. One of its five known 

 stations is in Ireland— Saintfield, Co. Down, where it was collected last 

 year by Rev. C. H. Waddell.
