A Prelhninary Survey of the Meteorology of Kimhcrley. 207 
Kenilworth derived from readings of a large observatory standard 
barometer — the readings being made three times a day, at VIII., XIV., 
and XX., civil time. The mean of the pressures at these hours is practi- 
cally the same as the mean of the hourly readings. 
The late Mr. G. J. Lee took a series of meteorological observations 
from 1890-7 at his ovv^n second-order station in Jones Street, Kimberley. 
His observations of pressure were made at VIII. and XX. with a small 
Fortin barometer, and considering the difference of altitude between 
Kimberley and Kenilworth, they compare very well with those of Kenil- 
worth. The Jones Street results have been computed and shown in Table 7. 
The table on the opposite page gives the respective monthly means for 1897. 
After reducing the Kimberley annual means to the Kenilworth level, 
and smoothing the values in threes by Bloxam's method, we have the 
following series, some corresponding values for Durban and Mauritius being 
added for purposes of comparison : — 
Kenilworth. 
Durban.

Thus the irregular oscillations of pressure of long period, in the 
southern anticyclone belt, affect Kimberley and Durban similarly, but not 
Mauritius.
