Section (c). — We have 7 cases, 3 followed by rain and 4 by dry 
weather ; wind was westerly. A similar argument holds here as in 
Section (b). 
Prediction. — Wet weather. 
Exception ; minor fluctuation in an anticyclone. 
DIVISION (2). 
Only one case occurs. 
DIVISION (3). 
Section (a). — This took place upon 24 occasions, and after 6 of them 
rain followed, but in no case was it expected. 
Section (b). — Here we have 20 cases, and rain followed only 1 of 
them. 
Section (c). — There were 22 cases, and only 1 day's rain. 
Prediction for Division. — Dry weather. 
SUB-GEOUP (K). 
This may be brought about by a decrease of pressure over the land 
between Clanwilliam and L'Agulhas ; sometimes the barometer rises at 
the Eoyal Observatory, due to the approach of an anticyclone. It is not 
rain-bringing, except in special cases. 
DIVISION (1). 
Section (a). — This occurred 6 times, and was followed by rain upon 
2 of them. 
Prediction. — Dry weather ; but if there is any indication that 
conditions which appear under Sub-group (A) are manifest, then 
there will be a great probability of rain. 
Section (b). — There are no cases. 
Section (c). — Here we have 5 cases, only 1 of which was followed by 
rain. 
Prediction. — Dry weather. 
DIVISION (2). 
No cases. 
DIVISION (3). 
Section (a). — No cases.
