✦ Synopsis

The most recent estimates of the composition of the primary radiation based upon the asymmetry and the latitude effect leave but a small margin for negatives and the most probable result is that all of the field-sensitive intensity at sea level is due to positives. Defining fl =-(j+ + j-)/(j+ --j-), from the latitude effect we find fl = 1.16 =I= 0.50 and from the north-south asymmetry fl = 0.8 =t= 0.3o. For first estimates see T. H.
