one-half of the book is devoted to descriptions of the various min- 
erals. The economic importance of the minerals is clearly pointed 
out, then the composition and general description is given, followed 
by the physical characters, action before the blowpipe, and similar spe- 
cies noted. A list of important localities is also added. ‘The impor- 
tant minerals are printed in ordinary type, while less important ones 
are printed in small type, thus assisting in the study and reference. 
The third part of the work will prove of great service to students who 
wish to acquire a practical knowledge of minerals in a short time, since 
they are apt to be confused by the mass of detail in the larger works. 
Part IV. 1s entitled determinative mineralogy and contains tables 
for rapid determination of the common minerals. There are four of 
these tables, the first containing minerals of metallic or sub-metallic 
lustre, the second with blowpipe confirmations of the same; the third 
containing minerals without metallic lustre and their blowpipe tests, 
and the fourth with the physical characters as confirmation of the min- 
erals of non-metallic lustre. G. PERRY GRIMSLEY. 
Memow of Sir Andrew Crombie Ramsay. By SiR ARCHIBALD 
GEIKIE Pp. 397. Macmillan & Co. Price, $4.00. 
The biography of so distinguished a scientist as Sir Andrew Crom- 
bie Ramsay prepared by so appreciative a friend and so charming a 
writer as Sir Archibald Geikie could hardly fail to be of interest to 
geologists and geographers. The author has succeeded admirably in 
making the geniality and enthusiasm of Sir Andrew apparent, as well 
as in setting forth the distinguished service which he rendered to 
the science of geology. The memoir is much more than a mere 
biography. Sir Andrew was intimately connected with the geological 
survey of Great Britain for forty years, and an account of his work 
and of his influence, such as this memoir presents, involves a sketch 
of the history of the geological survey of the United Kingdom. Not 
only this, but Sir Andrew’s connection with the survey brought him 
into such intimate relations with other geologists of his own and 
foreign lands, that his biographer has found it easy to weave into the 
memoir much general information concerning geologists and geolog- 
ical progress during the period of Sir Andrew’s activity. 
Portraits of a dozen of Sir Andrew’s associates have been introduced 
into the memoir. ‘These portraits are an attractive feature of the vol-
