structed. The five volumes by Daniel L. Hazard of the division 

 of terrestrial magnetism give the details in regard to these sev- 

 eral stations, with the observations that have been carried on 

 through 1904. An interesting series of charts is included giving 

 the records of magnetic storms, some of them of exceptional 

 intensity, which can thus be compared at the different points. 



2. Hypsometry : Precise Leveling in the United States, 1903- 

 1907. With a Readjustment of the Level Net and Resulting 

 Elevations ; by John F. Hayford and L. Pike. Pp. 280. — Fol- 

 lowing the publications on leveling by the U. S. Coast and Geo- 

 detic Survey, given in Appendix 8 for 1899 and Appendix 3 for 

 1903, the present paper gives in detail the progress made in 

 developing the level-net over the country. Since 1903, 2,500 

 miles of leveling have been added by the Survey, and 1700 miles 

 by other organizations. Of these, two lines in Minnesota and 

 two in Louisiana, with a total length of 314 miles, are spurs from 

 the net, while all other lines forni links, or parts of links, of the 

 net itself. A special chart shows the status of the net for 1 907.

6. Publication of the Works of Amedeo Avogadro. — The year 

 1911 will be the one-hundreth anniversary of the publication of 

 Avogadro's classic memoir upon the molecular constitution of 

 gases. The Royal Academy of Sciences at Turin proposes to 

 celebrate the occasion by the publication of a volume containing 

 his most important works and by the erection of a monument to 

 him at Turin. The Committee of the Academy appeals to all 

 chemists and physicists to aid in this movement to honor the 

 memory of a man to whom Science owes a great debt. The 

 President of the Executive Commission is Sen. Enrico D'Ovidio 

 of Turin. The members of the Committee in the United States 

 include the following : F. W. Clarke, W. W. Coblentz, Ar.
