REPORT. 
17 
stone of Northumbeiiarsd lias furnished the Museum with 
some new and very remarkable exhibitions of Fossil wood,^ 
in which the fasciculated texture of the monocotjledonous 
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 Y/akefield 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 ool render 
a more acceptable service to Geological Botany, than by 
assisting the researches of that accurate and skilful observer. 
To the MinerALOG icAL Cabinet lias been added an iinde- 
scribed variety of the mammillary Carbonate of Zinc,'*' from 
Keswick, the colour of v/hicli is a bright sii,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
