each ; wind was from the east.

DIVISION (3).

them did rain follow.

them. 
Section (b). — We have 6 cases, and only 1 day's rain. 
Prediction for Division. — Dry weather. 
SUB-GKOUP (G). 
By referring to the triangle, it will be evident that when pressure yields 
the most at Clanwilliam it must be due to summer type conditions. Pres- 
sure may have been so low at L'Agulhas that even with Clanwilliam 
falling the most the actual reading will be lowest at the former. This may 
lead to rain at the Eoyal Observatory. But under other conditions we 
should not expect rain. Possibly some might fall at L'Agulhas, but this 
would be purely coastal or Eastern Province rainfall. 
DIVISION (1). 
Section (a). — This happened upon 3 occasions, and on each rain 
followed.

on 2 it did not ; rain was expected on each occasion. 
Prediction. — Probable wet weather. 
Section (c). — This happened upon 4 days, and dry weather followed all 
of them. 
Prediction. — Dry weather. 
DIVISION (2). 
We have only 1 case, so can offer no comment.
