380 Reviews — Professor Cole's Aids in Practical Geology/. 



an annotated list of the contents of certain parts of a number of 

 periodicals, taken by countries. Each number is completed by an 

 index to the subject-matter and a list of the periodicals noticed in 

 that part. This latter is a useful feature. 



4. Dr. F. a. Bather, M.A.— On April 23 the Principal Trustees 

 of the British Museum appointed Dr. F. A. Bather to fill the Assistant- 

 Keepership of the Department of Geology, rendered vacant by the 

 promotion of Dr. A. Smith Woodward to the Keepership on the 

 18th December previous. 



5. Earthquakes in Greece. — It may not be generally known 

 tliat there is published a list of earthquakes observed in Greece for 

 the year. The list appears in Annales de V Ohservatoire Nationale 

 (TAthenes, edited by Professor Demetrius Eginitis. Volume iii, 1901 

 (4to, Athenes), contains the earthquakes recorded for the year 1899, 

 in chronological orders. In each case the time is given, its strength 

 noted, direction, length, and the name of the recorder. The utility 

 of this valuable record would be much enhanced if Professor Eginitis 

 would give an alphabetical index to the localities in future lists. 



6. Emendations of Ammonite Nomenclature. — Under the above 

 title, Mr. S. S. Buckman has issued an 8 pp. pamphlet of revision 

 of the nomenclature in his monograph on the Inferior Oolite 

 Ammonites published by the Paleeontographical Society. The 

 pamphlet, at first issued privately in June, has now (July) been 

 published, and is on sale at Norman, Sawyer, & Co., Cheltenham, 

 price one shilling. It contains numerous new generic and 

 trivial names.

Aids in Practical Geology. By Professor Grenvillb A. J. Cole, 

 M.R.I.A., F.G.S. 4th edition. 8vo ; pp. 431. (London : 

 Charles Griffin & Co., 1902.) 



WB were able to speak highly of this "eminently practical" 

 work on geology eleven years ago in our notice of the first 

 edition (Geol. Mag. for 1891, p. 230). We therefore welcome the 

 fourth edition, for it proves that the labours of the author have 

 been appreciated. Those of our readers who have not yet acquired 

 the book should know that it does not deal with economic geology, 

 but is intended as a companion to ordinary textbooks, and to give 

 instruction to the student in the methods of examining and deter- 

 mining minerals, rocks, and fossils. The work has been revised 

 throughout, and amongst the fresh information mention should be 

 made of that on the isolation of the constituents of rocks. The 

 author observes that " Few changes in nomenclature have been 

 introduced into this edition, and the limits of the names of rocks, 

 and even of fossil genera, have been kept as wide as possible." 

 This is right. Nomenclature is the bane of students and of 

 teachers of natural science, in respect of its ' kaleidoscopic ' changes ; 

 and Professor Cole has not been able to escape them altogether.
