THE WEATHER.

Barometer read twica daily, at 10 p.m. and at 8.30 a.m.j also, occasionally in timesof atmospheric disturbance. All dates reler to 10 a-in., and observations are those of the previous 24 hours. (*) At 8.30 a.m. (tj At 6.30 p.m. (Bth). (}) Wind, at N.W. Violent showers, especially in night, with occasional strong gusts of wind, a very low barometer, and generally cool weather. Approximate mean , temperature nearly the same as last year, one-tenth below the fifteen yeara' average ; differing from 1878 in warmer days and cooler nights, shewing rery little range from day to day. The 11th and 12th, which shew in the table for the absolute extremes of temperature, were also the days of highest and lowest mean_ for the twenty-four hours. The sun readings have ruled very low, owing not only to the period of the year, but also to the generally cloudy state of the atmosphere. On more than one night, and most noticeably on the 12th (Friday 11th), the terrestrial radiation thermometer on the grass in the open air read considerably above the instrument in the frame (minimum dry bulb, 41*7; terrestrial radiation, 45'1).

The rainfall of the week has been decidedly heavy, more than double the average, not falling on any day continuously for any length ef time, but in rushing showers of mostly short duration, often ao copious as to leave the waters lying in pools on the surface of even lately dug ground for several minutes before it was absorbed. Little rain fell on any day between sunriße and nooD, almost all bo two an noon and the sunriße following. These showers were often curiously local, sometimes very cold, mixed with sleet, or occasionally with bail. Tha wind has been very moderate throughout the week, and mostly uniform in its velocity and direction; one day E. and very light, the other six days W. and N. W., with a general average of nearly ten miles per hour. As above remarked, there were sudden violent gußis of great intensity and short duration.

The barometer has been steady-low the entire week ; falling rapidly from the point r«ached on the . morning of Sunday last (6th), and rising or falling little above or; below the levels of 29-5 and 29 "6. Since observation hour on Saturday, it has risen very rapidly with the southerly shift of wind, but may not stand at the point it has reaohed. 1 Averages for Month of July, 1864-78 : Barometer (corrected) 29*866 Approximate mean temperature ... 52*2 EaUfall (proportionate part for 1 week) 1*036 Elwtn- B.
