simpler and briefer, the treatment is much the same as that followed 
in the Handbook of von Zittel, the chapters in question having been 
prepared for that work by the self-same author. Here also new figures 
are inserted, a very striking one being Brongniart’s restoration of 
Meganeura, a dragon-fly having an expanse of 30 inches between tips 
of wings. The book concludes with a complete index of genera and 
subgenera. 
The present edition of the von Zittel places in the hands of every 
English-speaking student a good elementary text-book that has long 
been needed. It is significant that in the “ Eastman translation” so 
much American material has been introduced, and that so much 
revision has been done by American specialists. 
Regarding the work as a whole we may repeat what was said of the 
first part, that educators in general owe to Dr. Eastman a deep debt 
of gratitude for providing our college and higher schools with a “ trans- 
lated, revised, and enlarged edition” of the best manual of paleon- | 
tology that has ever been written. Professor von Zittel is to be 
congratulated, not only for the improvement presented by his new 
elementary text-book, but also, as shown by the results, for having 
entrusted the preparation of the translated edition to such excellent 
hands. CHARLES R. KEYES. 
The Gold Measures of Nova Scotia and Deep Mining. By E. 
R. FartpauLt. Canadian Mining Review, March 1899, 
Pp. 11, with 6 plates. 
E. R. Faribault, of the Canadian Geological survey, has lately 
announced the results of fifteen year’s work on the gold measures of 
Nova Scotia. These results are of great interest, both from a scien- 
tific and economic standpoint. 
The gold measures of Nova Scotia are confined to the meta- 
morphic Lower Cambrian quartzites and slates, forming a belt along 
the Atlantic coast from to to 75 miles wide. Intruding these rocks 
are large masses of granite occupying nearly a third of the superfices 
of the province. ‘These were intruded in Silurian time, after the fold- 
ing of the strata and deposition of the gold-bearing quartz, and need 
not be considered. The originally horizontal quartzites and slates have 
been folded into a series of huge undulations roughly parallel with 
the seacoast. The amplitude of the folds varies considerably, but
