REPORT.

is to be regretted that the additions to it have not been more 
numerous. Some useful accessions have been received from 
Cleveland 1 , from Whitby 2 , and from Ferrybridge 3 ; but, 
extended as the Society now is, and numerous as are the 
fossils which might be procured in all parts of the county, 
the supply would doubtless have been greater, were the 
members aware how much is still wanting to complete the 
excellence of this part of the Museum. 
The Council cannot conclude their account of the geolo¬ 
gical donations, without acknowledging the liberality of the 
Bristol Institution, and of the Geological Society of London, 
in allowing casts to be taken from some of the most remark¬ 
able organic remains in their possession. Casts have also 
been promised, of the fossil bones of Montmartre, by 
M. Cuvier, and of a highly valuable saurian specimen, by 
Mr. Chantrey. 
In Mineralogy, the Museum has continued to receive 
the assistance of some liberal friends. The addition of the 
greatest amount is that which has been made to the North 
American collection 4 : the most remarkable individual mine¬ 
rals presented are the Gaylussite from Lagunilla, 5 and 
the Chlorophaeite, found near Felton in Northumberland, 
filling cavities in the basaltic dyke. 6 An undescribed alu¬ 
minous mineral in the Society’s possession has been analysed,
