through his son. It consisted at that date of about 9000 specimens, all 

 of which were numbered and arranged. Its series of British minerals, 

 with the exception of Cornish specimens, was the finest known. The 

 collection was also rich in Norwegian minerals, and the series of chessy- 

 lite and idocrase were extraordinarily good. It also included specimens- 

 of twenty-seven meteorites which were at that time unrepresented in the 

 Museum.

Greville (Et. Hon. CHARLES FRANCIS, P.O.). [1749-1809] 



The Et. Hon. Charles Greville, P.O., F.R.S., of London, son of the 

 first Earl of Warwick, and nephew of Sir William Hamilton, died intestate 

 in the year 1809, and it became necessary to realise his property for 

 division among his next-of-kin. The property included a collection of 

 minerals which he had been forming for more than thirty years, and had 

 arranged in his house at Paddington Green. Its nucleus was the collection 

 of Baron von Born (<?..), which was purchased from him by Greville. 

 To this was probably added the collection of the Marchese Ippolito 

 Durazzo (q.v.~). Between 1794 and 1806 Count de Bournon (q.v.) gave 

 much time to the arrangement of Greville's collection, and during the 

 same period gave advice as regarded further acquisitions. The collection 

 became eventually the finest assemblage of minerals which had been seen 

 in England, and was declared by English mineralogists and Count de 

 Bournon in 1810 to be in most parts tqual, and in many parts superior, 

 to the best Continental collections. A sum of money \\ as specially voted 

 by Parliament for the purchase of the collection, numbering about 14800- 

 specimens, for the British Museum. The faceted stones of the Greville 

 collection did not form part of this purchase, but had been disposed of 

 separately; but the precious stones in their native condition were well 

 represented ; there were fine series of crystallised diamond, ruby, sapphire,, 

 emerald, topaz, and rubellite. It also included fragments of the following 

 meteorites : Barbotan, Cape of Good Hope, Elbogen, Ensisheim, Salles, 

 Tabor and Weston, all of which had been unrepresented in the Museum 

 Collection.
