Buckland's annual addresses when President of the Geological 
Society ; and the Institution of Civil Engineers, in October 
last, awarded a Telford medal in silver to Mr. Sop with for 
his communication on the use of such models in connection 
with civil engineering and geology. 
ELECTROTYPED COPIES OF FOSSILS. 
Mr. SopwiTH exhibited several specimens of fossils copied 
by the electrotype process, by Mr. T. B. Jordan, of the 
Museum of Economic Geology,* in London. The thin de- 
posit of copper which is formed on the wax or plaster 
cast from the original fossils, conveys an exact idea of the 
minutest details of structure, and Mr. S. pointed out that 
by these means correct copies of the best specimens of 
fossils could be multiplied to an indefinite extent, at a small 
expense, and every village museum might thus obtain elec- 
trotyped fossils, corresponding to those which adorn the 
cabinets of the Geological Society, or of the most careful 
amateurs. He had also received from Mr. Jordan some 
beautiful specimens of copies of medals, which were laid on 
the table, and attracted much attention ; and the application 
of this new and interesting art was shown to be capable of 
a still wider range, by an egg cup which had been entirely 
formed by the electrotype process. This specimen of Mr. 
Jordan's ingenuity shows very clearly that works of art 
of the most costly description can be multiplied to a 
great extent, and a richly ornamented urn, gold cup, or 
* This Museum, established by Government in Craig's Court, London, is 
under the direction of Sir Henry De la Beche, whose arduous and untiring exer- 
tions have for many years been devoted to the practical applications of Geology to 
Architecture, Agriculture, and the Arts, and by whose zeal and judgment this 
establishment promises to be one of the most valuable additions to the means of 
acquiring a scientific knowledge of the various qualities of stone — the processes 
used in various manufactures, and in the various and extensive applications of 
Economic Geology.
