2. Bulletin of the Seismological Society of America. Publi- 

 cation Committee : J. C. Beanner, A. C. Lawson, S. D. Town- 

 ley. Vol. I, No. 1, pp. 32, Stanford University, 1911. — The open- 

 ing number of the Bulletin of the Seismological Society, announced 

 a month or two since (see vol. xxxi, 247), has recently appeared, 

 and inaugurates a movement which is sure to be of great impor- 

 tance in the progress of this science in the country. The leading 

 article is by A. C. Lawson, and gives a brief review of the pres- 

 ent condition of seismology in the country, with practical sugges- 

 tions as to means for developing this further. This is followed 

 by a paper on the seismological work on the Pacific coast, by J. 

 C. Branner, and another by A. McAdie on the seismological 

 observations of the future. The earthquakes in Central New 

 Mexico of 1906 and 1907 are discussed at length by H. F. Reid. 

 Other contributions give a list of seismographs in America, and a 

 statement by J. B. Woodworth of the Gottingen nomenclature
