GALLEBY comprise fossils from all parts of England and from every geological 

 XI- formation. 



The small green labels mark the specimens actually figured in 

 the work. The collection was purchased by the Trustees of the 

 British Museum from Mr. J. de Carle Sowerby, January, 1861. 



It may be interesting to record that many of the latter parts 

 were illustrated by plates drawn by the late J. W. Salter, 

 A.L.S., F.G.S., for so many years palaeontologist to the Geological 

 Survey. When a youth, Salter was apprenticed to J. de Carle 

 Sowerby, who was at that time both a naturalist and an en- 

 graver. The youthful apprentice afterwards married his masters 

 daughter, and became, as is well known, one of the most brilliant 

 palaeontologists in this country. 



Another curious but small series represents the "types" or 

 "figured specimens" of Konig's ^^ Icones Fossilium Seottles.^' 



This illustrated work, on miscellaneous fossils in the British 



Konig's Museum, was prepared by Mr. Charles Konig, the first Keeper of 



irpT^* the Mineralogieal and Geological Department, after its separation 

 from the General Natural History collections in 1825. 



case^e ^^^ engravings are rough, but characteristic, and the first 



"century" (or 100 figures of fossils) is accompanied by descrip- 

 tions; the plates of the second "century" have names only, and 



Gilbertson °^ descriptions are published with them. 



Collection, A far more important collection is that known as the 



^®^^- Gilbertson Collection. 



Table- i^ igSG Professor John Phillips published vol. ii of his " lUus- 



cases , 



15 & 16. trations of the Geology of Yorkshire," which is devoted to the 



"Mountain Limestone District." In the Introduction he writes 



as follows: — "My greatest obligation is to Mr. Wm. Gilbertson, 



of Preston, a naturalist of high acquirements, who has for many 



years explored with exceeding diligence a region of Mountain 



Limestone, remarkably rich in organic remains. The collection 



which he has amassed from the small district of Bolland is at this 



moment unrivalled, and he has done for me, without solicitation, 



what is seldom granted to the most urgent entreaty; he has sent 



me for deliberate examination, at convenient intervals, the whole 



of his magnificent collection, accompanied by remarks dictated 



by long experience and a sound judgment." Gilbertson had 



proposed to publish on the Crinoidea himself, but his sketches, as 



well as his specimens, were all placed at Professor Phillips' disposal.
