we notice over 60 are from the United States, among them are perhaps 
included a few that when more thoroughly investigated will prove to have 
no claim to meteoric origin. 
The book also contains a catalogue of the various European and Amer- 
ican collections of meteorites, and the number of localities represented in 
each cabinet. Among the public collections containing specimens from 
more than 50 localities are the museums of Vienna (194), London 
(British Museum, 190), Géttingen (125), Paris (Garden of Plants, 53). 
The largest private collections are those of R. P. Greg, Manchester, Eng., 
numbering 191—Reichenbach, Vienna, 176—C. U. Shepard, Amherst 
College, 151—Nevill, London, 101—Auerbach, Moscow, 76—Neumann, 
Prague, 61—J. Lawrence Smith, Louisville, 60. 
This work is exceedingly valuable to all who are occupied in the study 
of meteorites. In most cases it gives accurate references to original 
authorities, and full citations of the literature of the subject. We have 
noticed some minor errors in the statements made, but it is almost impos- 
sible to bring together such a mass of material without committing an 
occasional oversight. The author deserves the thanks of all interested in
