tremors, &c. On all of these questions Mr. Mellard.Eeade advances 

 views which are well worthy of the consideration of geologists. 



The work is very amply illustrated by no less than forty-two 

 plates containing many figures. Some of these are reproductions 

 of the sections and maps published by the United-States Geolo- 

 gical Survey and the Second Geological Survey of Pennsylvania, 

 while a few are taken from the sections published by our own Geo- 

 logical Survey. But the majority of the illustrations are repro- 

 ductions by photo-lithography of the author's own drawings and 

 sepia-sketches. 



We very heartily recommend this valuable work to the attention 

 of geologists, as an important contribution to terrestrial dynamics. 



Descriptive Catalogue of a Collection of the Economic Minerals 

 of Canada. 8vo. London, 1886. 

 This Catalogue of one hundred and seventy pages is one of the 

 many useful works published in connection with the Colonial and 

 Indian Exhibition, It is compiled by the Geological Corps of 

 Canada, acting under the direction of Dr. A. II. C. Selwyn. 

 Although essentially a list of the specimens exhibited in the Cana- 

 dian Collection, the minerals and rocks are fully described, with 

 their properties, localities, and the geological horizon from which 

 they were obtained, thus rendering the work of permanent value as 

 a reference book to the mineralogist, geologist, and prospector. 

 The districts represented are — British Columbia, North-west 

 Territories, Manitoba, Ontario, Quebec, North-east Territory, New 

 Brunswick, Prince-Edward Island, and Nova Scotia; and from 

 these upwards of 700 specimens are described. The more impor- 

 tant minerals, as Coal and Apatite, receive especial attention ; and 

 the notes on the latter are rendered more valuable by the addition 

 of plans and sections illustrative of the occurrence of the mineral 

 and of the two finest examples that were exhibited. The work is 

 divided into eleven sections, the most noteworthy of which are the 

 following : — I. Metals and their Ores ; II. Materials used in the 

 Production of Heat and Light ; III. Minerals applicable to certain 

 Chemical Manufactures and their Products ; IY. Mineral Manure ; 

 VII. to X. Materials applicable to various Constructions, Eine Arts, 

 Jewellery, &c. 



Journal and Proceedings of ilie Boyal Society of New South Wales 



for 1885. Vol. XIX. 8vo. Sydney, 1886 : 240 pp. 

 This volume contains eleven papers, besides the usual valuable 

 Meteorological appendix, and a Eainfall Map for 1881. In the 

 Anniversary Address the President, Mr. H. C. Eussell, gives some 

 important notes on the movement of the " East Coast, if not all 

 Australia," quoting the late Bev. W. B. Clarke, Mr. John Kent, 

 Mr. Ellery, and others, and giving the results of his own observa- 

 tions for twelve years past. " The evidences," Mr. Eussell says, 

 " for elevation and subsidence of the land are about equal ;" and, 

 as accurate observations have as yet been made only at Sydney, where 

 in the twelve years no appreciable change has been noticed, it is
