VII. — A cq%iisitions. 



1,403 specimens have been acquired, namely : — 



620 minerals, 667 rocks, and 116 meteorites. 



Particularly noteworthy amongst the acquisitions during 

 the year are the superb specimens of minerals from the Walker 

 Collection, some of the finest of which were pr<^sented by 

 Mv. F. N. A. Fleischmann. The Walker Collection was brought 

 together for the most part by Mr. Isaac Walker (1794-1853), 

 of Southgate, Middlesex, who purchased the majority of the 

 finest specimens from Henry Heuland at his public sales of 

 minerals held between 1826 and 1847. The specimens now 

 acquired by the Museum therefore include some of the most 

 remarkable examples of minerals discovered or ofi'ered for sale 

 at that time. 



Exchanges of specimens have been made with the Museum 

 National d'Histoire Naturelle, Paris (through Prof. A. Lacroix) ; 

 and the Servico Geologico e Mineralogico do Brazil (through 

 Prof. Orville A. Derby ).
