Minerals. 371 



in its magnificent series of British minerals, of which, if the 

 Cornish minerals be excepted, it was the finest collection known ; 

 the Manual of the Mineralogy of Great Britain and Ireland, by 

 R. P. Greg and W. G. Lettsom, published in 1858, was based 

 on that material. The collection was also peculiarly rich in 

 Norwegian minerals, and the series of chessylite and idocrase 

 were extraordinarily good. The specimens had been catalogued 

 and numbered before the collection was purchased by the 

 Trustees. 



A series of Italian minerals : purchased. 



A large mass of native copper from Lake Superior : purchased. 



A selection of specimens from the collection of Prof. Nuttall, 

 including a very fine group of crystals of kyanite from Massa- 

 chusetts : purchased.

A series of specimens from the Campbell collection. In 1861, 

 on the death of Mr. James R. Campbell, of Cheltenham, the 

 Trustees were permitted to make a selection from the well-chosen 

 specimens, upwards of 3000 in number, which had been brought 

 together by him ; as a result nearly 500 specimens were pur- 

 chased in this and the following year, and further, three remark- 

 able specimens were presented by his widow ; one of the latter 

 being a radiating group of crystals of erythrite, of a rich crimson 

 colour, on a matrix of crystallised quartz, from Schneeberg in 

 Saxony. 



Very large crystals of rutile from Lincoln County, Georgia : 

 purchased.
