The cosmic-ray intensity during the 18th and 19th solar cycles is examined in the light of Gnevyshev's suggestion of the presence of two maxima in each solar cycle. The 18th solar cycle has two prominent and widely separated cosmic-ray minima corresponding in phase with the two maxima in Bartel's Ap
With 3 figures. (Received 196G October IS) I t is shown from measurements of type I11 bursts a t 234 MHz, I I I MHz and 23 MHz during the foregoing solar cycle that the type I11 activity has a relative minimum in 1959 and apparently a second maximum in 1960. This is in accordance with the statement
Each 11-years cycle of solar activity consists of two processes with different physical properties. The variety of shapes of the 11-years curves depends on the way these processes overlap. All events in the photosphere, chromosphere and corona, and all kinds of emissions like the radio-and corpuscu
