British East Africa.— Observations have been received
from thirteen stations. Unfortunately, owing to the disturbed
state of the country and to administrative changes, some of
the registers are imperfect. The Foreign Office has met
with the wishes of your Committee in the most gratifying
manner. Instructions have been given by Mr. Hardinge,
her Majesty’s Commissioner, to have meteorological returns
kept, and these will be sent to us for publication.
Three sets of instruments (including barometers and
anemometers) have been forwarded by the Foreign Office
to Uganda, and since the beginning of this year observations
on the water-level of the Victoria Nyanza are being made by
means of gauges erected at Port Alice and Port Victoria.

The barometrical observations have been reduced to 32° and corrected for gravity, but have not been reduced to sea-level.
The mean temperature is assumed to be the mean of all max. and min., and is therefore too high.
