IX. — Micropetrology for BEaiNNERS : an Introduction to the trsE 

 OF the Microscope in the examination of thin sections of 

 Igneous Rocks. By J. E. Wtnfield Rhodes, B.Sc. 8vo ; 

 pp. XV, 126, with 1 plate and 26 text-illustrations. London : 

 Longmans, Green & Co., 1912. Price 2s. 6d. net. 



THIS little book, introduced to the public in a preface by Mr. C. H. 

 Sidebotham, F.G.S., will prove a useful primer for the student, 

 and will no doubt be an aid to those going up for examination in 

 petrology. The methods of preparing thin slices of rock and of 

 identifying the minerals under the microscope, the composition of the 

 principal rock-forming minerals and of the igneous rocks, including 

 such forms as Laurvigite, Foyaite, Ditroite, Hyperite, Markfieldite, 

 and Teschenite, are treated systematically and concisely. Finally, 

 there is a glossarial index. 



X. — The Yoyage of the Discoveby. By Captain Robert F. Scott, 

 C.V.O., R.N. Re-issue, 2 vols. 8vo ; pp. xiv, ix, 410, 387, 

 with 12 plates and 2 maps. London : Smith, Elder & Co., 1912. 

 Price 3s. &d. each vol. 

 rpmS work was originally published in two large octavo volumes 

 X in 1905. It has now been re-issued in smaller size and at 

 a price which will be welcome to many geologists and students in 

 different branches of science, as well as to a wide circle of other 

 readers interested in this fascinating record of arduous and successful 

 exploration. The text has been reproduced intact, with the summary 

 of the geological observations by Mr. R. T. Ferrar, and the account of 

 the whales, seals, and birds by Mr. E. A. Wilson. To the student 

 of glacial phenomena the whole narrative is full of instruction on ice 

 and ice-action, and the only regret felt will be in the fact that but 

 few of the original illustrations have been reproduced. 



XI. — Brief ^Notices. 

 1. Mineralogical Notes. — Under the title " Mineralogical Notes, 

 Series 1 ", the United States Geological Survey has published 

 Bulletin 490 (Washington, 1911), by Dr. Walderaar T. Schaller. 

 This is a continuation of Bulletin 262 (1905), and contains the results 

 of further research carried on by the author in the chemical laboratory 

 of the Survey. Some of the papers were originally written and 

 published in conjunction with members of the Survey ; acknowledg- 

 ment has been made to these, and some papers have been re-arranged. 

 Among the minerals considered chemically, hulsite, paigeite, jamesonite,
