Affiliated Societies Meet

Two affiliated scientific societies, the Mineralogical Society of America and the American Paleontological Society, will hold their annual meetings in Cambridge in conjunction with the Geological Society. Exhibits of material of each of the three fields will be arranged in the common rooms of the Union, under the direction of L. D. Leet, instructor in Seismology. Excursions to various points of geological interest in New England will also be conducted for visitors from other parts of the country. Numerous scientific papers will be read at the meeting, on all phases of Geology, Paleontology, and Mineralogy. These will later be published in the Bulletin of the Society.
