SUB-GEOUP (F). 
Similar conditions to those affecting Sub-Group (E) can bring about 
this, with a high-pressure area pushing from the west or south-west and 
wedging across the peninsula. 
DIVISION (1). 
Section (a). — Only 1 case. 
Section (b). — No cases. 
Section (c). — There were only 3 cases, 2 being followed by very slight 
rainfall. 
Prediction for Division. — (Provisionally) — Dry weather. 
DIVISION (2). 
Section (q). — Only 1 case. 
Section (b). — Here we have 4 cases, followed by dry weather. 
Section (c). — This happened upon 18 occasions, and after 13 of them 
dry weather followed ; out of the 5 exceptions the falls were below 
0'05 in. 3 times, and the other 2 were abnormal, and no rain was 
expected. 
Prediction for Division. — Dry weather. 
DIVISION (3). 
Sections (a), (b). — No cases. 
Section (c). — There were 6 cases, and only 1 followed by dry 
weather ; on this day rain was expected. 
Prediction for Division. — Wet weather. 
SUB-GEOUP (G). 
Here we have conditions bearing a relationship to Sub-Group 1, (A) ; 
where L'Agulhas falls most and Olanwilliam least. In some cases it will 
be seen that the barometer at L'Agulhas actually falls while others rise, 
and these will be specially considered. This condition is one which 
succeeds the passing of a winter type depression, or the advance 
of high-pressure areas from the north or north-west ; sometimes 
a high-pressure area is pushing down from the north or north-west 
while a depression is affecting the south, and we have thus a com- 
plication.
