VII. — A cquisitions. 



1,780 specimens have been acquired, namely : — 



1,187 minerals, 585 rocks, and 8 meteorites. 



The most interesting of these acquisitions, from a historic 

 point of view, is the old collection of Minerals formed by 

 Thomas Pennant (see p. 225). With the exception of a few 

 specimens, this has not been distributed in the General Collec- 

 tion, but has been retained in its original oak cabinet as a 

 collection of historic interest, illustrating an old natural history 

 system of classification. 



Exchanges of specimens have been arranged with Dr 

 Latteux, of Paris, and Mr. James Broadhead, of Darlington.
