excepted day rain was expected, and it rained at L'Agulhas. 
Section (c). — This happened upon 5 occasions, 3 being followed by rain 
and 2 by dry weather ; the 2 exceptions were due to the fact that the 
movement was merely a fluctuation in an anticyclone in each case. 
Prediction for Division. — Dry weather. Exception. — -Fluctua- 
tion in an anticyclone. 
SUB-GEOUP (J). 
This is a condition which can follow in the rear of a winter type 
depression, or it may be that , such a depression is still at L'Agulhas and 
pressure banking up to the north-west. Again, it may be due to the 
banking up on the north-west of an existing high-pressure area. It is 
akin to Sub-Group (G). 
DIVISION (1). 
Section (a). — There is only 1 case. 
Section (b). — Only 2 cases, followed by dry weather.
