260 Scientific Intelligence. 



Ocean at Seattle. Appendix III contains an account of mag- 

 netic observations made under the charge of Dr. L. A. Bauer ; 

 this special report has also been issued in separate form. It is 

 stated that there have now been obtained exact magnetic data 

 for determining the distribution of the magnetic elements and 

 their secular change throughout the United States, so that a new 

 set of charts may soon be expected for the year 1905. In regard 

 to the secular change of magnetic declination, it is noted that 

 at present the line of no annual change does not differ much from 

 the agonic line, and that in general both the east and west decli- 

 nation are increasing.

9. Elementary Mechanics; by George A. Merrill, B.S., 

 Director of the Wilmerding School of Industrial Art, San Fran-

 The usual topics treated in a work of this character are here 

 presented with much clearness and freshness. The author relies 

 on illustrations and numerical applications to the exclusion of all 

 formal proofs. The numerical exercises are well chosen but lim- 

 ited in number.
