โœฆ Synopsis

A corpuscular ray may be absorbed: A. with a definite range, or B~ more or less exponentially with an absorption coefficient. The experiments discussed seem to require mechanism B with x = 0.3 per meter water for primary cosmic rays of energy around 10 lยฐ volt in air, but mechanism A for the samerays in lead and for rays of energy around l0 n volt in water. An interpretation reconciling these results is attempted.

In the following pages the results are given of the measurements of the number and the average life of ions, and of the number of charged and uncharged condensation-nuclei in the air on the open sea. The number of fast ions was constantly recorded with the aid of an E be r t-aspirator combined with

From the combination of Latitude effect and East--West asymmetry it is possible to conclude whether there are positive and negative primaries. Our observations give a ratio of the number of positives to negatives of about 2 to 1, between two given energy limits. A north excess of 4% is found in Ban
