The Carnegie Institution of Washington will continue to cooperate in the 
seismologie work and investigation of crustal movement in California. Special 
attention will be paid to the development of new instruments for the measure- 
ment of small earth tremors. An interesting feature of the recent exhibit at 
the Institution was a map showing the location of faults in California. The 
production of this map was made possible by the cooperation of scientific and 
mercantile interests. It will be published in final form by the Seismological 
Society of America. 
Two destroyers of the U. 8. Navy are engaged in making sounding measure- 
ments off the west coast of the United States with the “sonic” sounding appa- 
ratus. Parallel runs are being made at distances of five or ten miles and 
soundings are taken up to the two thousand fathom mark. The object is 
a complete topographic map of that part of the bottom of the sea. 
The Petrologists’ Club met on Tuesday, December 19, at 8 p.m. Dr. 
N. L. Bowen spoke on The action of magmas on autolithic and xenolithic 
material. He reviewed the various possible directions of crystallization and 
subsequent reaction between liquid and solid phases, and thus accounted 
for the various series of igneous rocks which are found in many localities.
