The intensity-time curves for cosmic rays recorded at some 30 stations distributed all over the world are examined for structure in the recovery period from the third in a series of three closely spaced Forbush type decreases which occurred in the middle of July 1959. It is shown that the structure of mtensity peaks is regular and that these occur at each station at the same effective local time. It is fourd that this is consistent with the hynethesis that recovery from a very deep Forbush type decrease is first apparent in directions making 15 and 165 deg with the sun-earth line, respectively. The analyses suggest further that during recovery from this deep Forbush decrease, temporary openings appeared in the intensity depressing mechanism which allowed intensity increases in limited directions.
