* Barometer readings reduced to 32° Fah., and to sea level. + Inches of mercury. { Saturation, 100. § For7 years only.  ‘ +” indicates that the temperature has been higher; “—” that it has been lower than the ayerage 
for 14 years, inclusive of 1888. The monthly means are derived from readings taken every 4th hour, beginning with 3h. 0m, Hastern Standard time. The anemometer and wind vane are on the summit of Mount Royal, 57 feet 
above the ground, and 810 feet above sea level. 
The greatest heat was 88.1 on June 22nd; greatest cold 2-4 below zero on February 10th; extreme range of temperature was therefore 112.5. Greatest range of the thermometer in one day was 50-1 on Jan. 13th; least 
2.3 0n Noy. 28th. The warmest day was June 24nd, when the mean temperature was 77.52. The coldest day Feb. 10th, when the mean temperature was 15.90 below zero. The highest barometer reading was 30.865

the greatest velocity in gusts was at the rate of 90in. p. h. for 3 miles, and 110m. p. h. for] mile, on March 18th. ‘Lhe total mileage of wind was 139,303. The resultant direction of the wind forthe year-is S. 748 W., and the
