the Cambrian. When these worn-down ranges are covered by un- 

 -disturbed Cambrian strata, as in the vicinity of St. Petersburg, we are 

 compelled to conclude that the ancient folding has not been continued 

 or renewed since an extremely remote period. In these regions, as 

 compared with those where recent sediments are involved in the 

 folding, it would seem that the earth is slumbering or as if the folding 

 force had become extinct." 



Eeference is also made to areas where the mainland is accompanied 

 by trend-lines of folding, and to others where this is not the case. 



The main body of the work is taken up with the great structural 

 features of Northern and Central Asia and Europe, and with the 

 evidence in certain regions of repeated folding or reconstruction. The 

 Asiatic folding is shown to be connected through the Caucasus with 

 that of Europe, while the system of movements between the Arctic 

 Ocean and the Mediterranean is not to be separated from that of 

 Eastern Eurasia. 



II. — The Philippine Islands. 



The Mineral Eesoueces of ihe Philippine Islands, with a 

 Statement of the Peodtjction of Commercial Mineral Products 

 DURING the tear 1907. Issucd by Warren D. Smith, Department 

 of the Interior, The Bureau of Science. 8vo ; pp. 39, illustrations 

 and maps. Manila, 1908. 



^riHIS is of necessity a preliminary account of work done, and it 

 J_ will be sufficient to call attention to the contents which follow : — 

 The Non-metallic Minerals, by W. D. Smith; Metallic Mineral 

 Eesources, by Maurice Goodman ; Statistics, by W. D. Smith ; Mining 

 and Geological Notes on a portion of North- Western Mindanao, by 

 H. M. Ickis ; Mining Prospects on and near the Zamboanga Peninsula 

 (brief summary of the geology), by W. D. Smith ; Summary of the 

 chief characteristics of Philippine Ores, by W. D. Smith; Summary 

 of the chief characteristics of Philippine Coals, by A. J. Cox. One of 

 the maps shows the principal mineral districts of the country. We 

 hope soon to possess a sketch-map of the geology of the whole group, 

 which should prove of especial interest with regard to Japan on the 

 one hand and the Javan-Bornean group on the other. 



III. — South African Paleontology. 

 The Invektebrate Fauna and Paleontological Eelations of the 

 TJitenhage Series. By F. L. Kitchin, M.A., Ph.D. Ann. South 

 African Museum, vol. vii, pt. ii, pp. 250, 10 plates. 8vo. Cape 

 Town (West, Newman, & Co., London), 1908. Price 12s. Qd. 



APOETION of this volume is devoted to descriptions of fossils 

 collected by the members of the Geological Survey of Cape 

 Colony and others. We hope the author has sent a copy of his work 

 to the Stationery Office in London, in order that they may see how 

 Cape Colony produces its prints and plates, which are quite in accord 

 with the importance of the subject. 



The collection here described was obtained mostly by Messrs. Eogers
