The total range of temperature was, therefore, 4G dejj, the mean daily range being Jl'-kdeg. Tho mean temperature of evaporation was 4b" 5 deg, and of the dewpoint &0:3 deg.' The mean .degree of humidity in the atmosphere was 64—saturation being represented by =lfl!>> whicbLHrns'reached on the 2nd and ,4th; the\yjd*%f.ibns :jn,the.hygrometrical readings weTe'-veT^»fem'arfeabte. u i?ainy weather and strong winds' dbrituni«Fto' prevail.

A cyclonic. storm 'occurred on the 6th, 7th and Bth, and a heavy fall of rain on the night of the Hth. The extreme dryness of tlie*air during the four last days • was almost unprecedented; —on the 29th the rcla-; tive humidity decreased to -45, and, on *fac -30th, even to 39.
