stone of NoTthumberlaiid has furnished the Museum with 

 some new and very remarkable exhibitions of Fossil wood,* 

 in which the fasciculated texture of the monocotyledonous 

 plants is beautifully preserved ; but which show also some 

 indications of a radiated structure, such as belongs to the 

 dicotyledonous tribes. To the Yorkshire Collection, -has 

 been added a sandstone cast of a gigantic Lepidodendron 

 from the coal-field near Wakefield ;^ and the impressions of 

 several new kinds of cycadiform plants and fernsj from the 

 strata near Scarborough, (in some of which the fructification 

 may be discerned,) have been presented by an Honorary 

 Member ^ of the Society, who has often contributed to its 

 Museum. Of these plants the Council have procured dupli- 

 cates, and have transmitted a well defined series to M. 

 Adolphe Brongniart, conceiving that they could not render 

 a more acceptable service to Geological Botany, than by 

 assisting the researches of that accurate and skilful observer. 



To the MiNERALOGicAL Cabinet has been added an unde- 

 scribed variety of the raammillary Carbonate of Zinc,* from 

 Keswick, the colour of which is a bright su,lphur yellow, 

 and which has been found, upon analysis, to contain Manga- 

 nese ; and some specimens of stalactitic Chalcedony in 

 •whinstone have been presented, * from the basaltic dyke 

 which crosses the northern part of this county. A valuable 

 contribution has been made to the ores of Tin ^ ; but it is to 

 be regretted, that a large proportion of the Cornish minerals
