We now come to an important group, namely, Division (3) from each 
of the Sub- Groups (E), (G), and (J) ; these we must place together, owing 
to their similarity of conditions. 
Let us first get at the actual facts. 
SUB-GEOUP (E). 
Section (a). — 2 cases, 1 followed by rain. 
Section (b). — 3 cases, each followed by rain. 
Section (c). — 5 cases, each followed by rain. 
SUB-GEOUP (G).

Section (b). — 24 cases ; on all but 1 wind was west ; on 13 days rain 
followed and after 11 dry weather.
