Gilbertson (WILLIAM) 



In the second volume of his " Illustrations of the Geology of York- 

 shire," 1836, Professor John Phillips writes as follows : " My greatest 

 obligation is to Mr. Gilbertson of Preston, a naturalist of high acquire- 

 ments, who has for many years explored with exceeding diligence and 

 acumen 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. He had proposed to publish an 

 account of his discoveries, and especially of the Crinoidea for which no 

 man in Europe had equal materials, and had made a great number of 

 careful drawings for the purpose ; but all these, as well as the specimens, 

 he placed at my disposal a striking proof of liberal and genuine devotion 

 to science. An attentive examination of this rich collection rendered it 

 unnecessary to study minutely the less extensive series preserved in other 

 cabinets." 



"Most of the figures of fossils are taken from specimens in Mr. 

 Oilbertson's collection, because these were generally the best that could 

 be found." Gilbertson was a pharmaceutical chemist and obtained his 

 specimens largely by purchase, thus acquiring the collection of Dr. 

 Alexander Moore of Preston, which included many specimens figured in 

 Sowerby's " Mineral Conchology." He presented a few crinoids to the 

 Geological Society in 1826 and in 1841, but in the latter year the rest of 

 his collection was purchased by the Trustees. It consisted of 2646 

 specimens, thus distributed: Corals, 103; Echinoderms, 613; Bivalves, 

 1041 ; Univalves, 810 ; Crustacea, etc., 79. In addition to the specimens 

 from Bolland are some from the Coal Measures of Lancashire. As the 

 collection was purchased by Dr. J. E. Gray and was for many years 

 retained in the Zoological Department, most of the specimens bear the 

 circular register ticket of that department, replacing Gilbertson's original 

 numbers. Labels in faded brown ink in the hand-writing of Phillips, 

 and signed <J>, are occasionally preserved. The collection was accompanied 

 by a detailed MS. list, which denoted by "P." the specimens figured by 

 Phillips, as mentioned above ; by " Z. J.," the blastoids figured by 

 G. B. Sowerby in the Zoological Journal ; by " S." or " Sow," specimens
