SCIENCE. 



[N. S. Vol. XX. No. 520. 



distance from its origin or centrum, is er- 

 roneously defined as ' the intensity at tlie epi- 

 center'; and the diagram on page 186 indi- 

 cates the intensity of a shock in the locus 

 technically called the pleistoseist as about 

 four ninths of its intensity at the epicenter, 

 whereas the text shows the ratio to be three 

 fourths. Slips of this character, which might 

 have been eliminated by more careful revision 

 of copy and proof, will doubtless be avoided in 

 subsequent editions. They detract but slight- 

 ly from the general value of the work, which 

 may be commended to the public as a lucid, 

 attractive, and at the same time scientific 

 presentation of a subject so difiicult that its 

 modern aspect is little understood outside the 

 circle of its special students.
