ABSTRACT
The prospect of observing solar neutrinos by means of the inverse beta process 37Cl(v, e −)37Ar induced us to place the apparatus previously described 1 in a mine and make a preliminary search. This experiment served to place an upper limit on the flux of extraterrestrial neutrinos. These results will be reported, and a discussion will be given of the possibility of extending the sensitivity of the method to a degree capable of measuring the solar neutrino flux calculated by Bahcall in the preceding paper. 2
