358 Minerals. 



gave the name columbium. The collection, which consisted of 

 nearly 7,000 specimens, mostly small, was particularly useful in 

 its representation of British minerals. Further, Mr. Hatchett, 

 in the course of his travels on the Continent and by means of 

 correspondence, had obtained many good illustrations of foreign 

 minerals. From Count Apollos de Moussin Poushkin, for 

 example, he had received a large number of Russian specimens, 

 a manuscript list of which is preserved in the Department. 



In the same year, 1799, on the death of the Rev. Clayton 

 Mordaunt Cracherode, F.R.S. [1730-1799], of London, who had 

 been elected a Trustee of the Museum in 1784, a fine collection 

 of books, prints, coins, medals, gems, minerals and shells came 

 to the Trustees by bequest. The mineral specimens were many 

 of them choice examples ; as may be estimated from the fact 

 that, though only 838 in number, their cost to the collector

 the far more extensive collection which had been formed by 

 Mr. Hatchett. There is a detailed manuscript catalogue of the

 labradorite and lapis lazuli ; crystallised specimens of blende, 

 tetrahedrite, argentite, pyrargyrite and heulandite.

The Rt. Hon. Charles Greville, P.C., F.R.S. [1749-1809], of
