is to be regretted that the additions to it have not been more 

 numerous. Some useful accessions have been received from 

 Cleveland ^, from Whitby % and from Ferrybridge ^ ; 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 *: the most remarkable individual mine- 

 rals presented are the Gaylussite from LaguniUa,^ and 

 the Chlorophaeite, found near Felton in Northumberland, 

 filling cavities in the basaltic dyke.® An undescribed alu- 

 minous mineral in the Society's possession has been analysed.
