unusual was at once recognized as such, and was brought to the 

 notice of the proper specialist. Consequently Carboniferous 

 palaeontology owes much to him, not only by reason of his own 

 •contributions to the literature, but also by the material which he 

 made available for other workers. Many rarities were obtained hj 

 •an ingenious method (described by Moysey in the ' Geological 

 Magazine,' dec. 5, vol. v, 1908, p. 220) by which the refractory 

 nodules containing the fossils were heated, soaked, and then alter- 

 nately frozen and thawed until they cracked readily. One of his 

 palseontological papers was published in our Quarterly Journal for 

 1910, and others appeared in the ' Geological Magazine.' He also 

 contributed a comprehensive appendix on the fossils from the 

 Derbyshire & Nottinghamshire Coalfield to the Geological Survey 

 Memoir on the district (1913). He joined our Society in 1907, 

 and in 1915 a portion of the Lyell Fund was awarded to him in 

 recognition of the value of his work. Shortly before his death, 

 he presented the whole of his collection of fossil plants to the 

 Sedgwick Museum, Cambridge, and the animal remains to the 

 Museum of Practical Geology at Jernvvn Street, London. 



Temperamentally unobtrusive, his amiability and quiet self- 

 abnegation gained for him the affection of all who had the privilege 

 of his personal acquaintance. 



From our Foreign List we have lost two Members and two 

 Correspondents, of whom three were citizens of the United States. 



By the death of Gboye Kabl Gilbebt American science 

 sustains a heavy loss, and a notable figure disappears from the 

 geological world. Born on May 6th, 1843, at Rochester (N.Y.), 

 Gilbert was educated in the same city. His University studies 

 were classical, but his natural endowments clearly marked him out 

 for a scientific career. His first opportunity came when he was 

 appointed an assistant on Wheeler's Survey of the Territories West 

 of the 100th Meridian, and in 1 871-73 he surveyed considerable 

 areas of Nevada, Utah, New Mexico, and Arizona. Later he was 

 attached to the Geographical & Geological Survey of the Rocky- 

 Mountain Region, and in 1875-76 made a stud}' of the Henry 

 Mountains of Utah. His report on this district, issued in 1879, 

 at once gave him an assured reputation ; for, in addition to a lucid 

 exposition of the laccolitic type of intrusion as there exemplified, 

 lie put forward an analysis of the processes of erosion and land-
