TO STUDY ROCK STRATA

P. E. Raymond, Assistant Professor of Palaeontology, accompanied by Professor Twenhofel of Kansas University, will go to Western Russia and southern Scandinava to study certain of the older sedimentary rock strata in comparison with strata of the same age in this country. Since similar types of animals are found fossilized in European and American rocks, it is possible that Professor Raymond's comparison of the strata will prove that these animals came from Russia and Scandinavia to North America.

The expedition is one of a series of scientific investigations which have been carried out in the last few years through the fund given in 1907 by a number of graduates in memory of the work done by Professor N. S. Shaler.

Another expedition under Professor W. M. Davis '70 has recently left San Francisco for the South Sea Islands, where a study of the formation, elevation, and subsidations of coral reefs will be made.
