the normal and was the coldest year since 1875. The devi- 

 ation in temperature for the year is almost entirely due to 

 the very low temperatures of the months of February and 

 March, which, as will be seen on inspection of the table, 

 made the very marked departure of over 10 ° below the 

 mean. August and September were also considerably below 

 the average. The year may be described as having a very 

 cold winter, a cold summer, and a spring and autumn of 

 average temperature. The greatest heat 87°. 1 was on July 

 17th, the greatest on the records of the past eleven years 

 is 93°. 9. The lowest temperature, 21°.3 below zero, was on 

 Jan. 22nd, while the lowest on the records is 26°.0. The 

 greatest range of the thermometer on one day was 35°. 9 on 

 April 23rd, and the least range 3°. on JSTov. 6th. The mean 

 temperature of the warmest day, July 30th, was 75°. 5 and 

 that of the coldest day 15°. below zero. The highest 

 barometer reading was 30.747 on Jan. 23rd, and the lowest 

 29.104 on Jan. 12th. The extremes of barometric pressure 

 which have been recorded here in eleven years are 30.999 

 and 28.766. The average weight of vapour in the air was 

 slightly less than the lowest in eleven years, the lowest 

 value being 0.234 for 1883. The driest state of the air was 

 on May 29th, when the relative humidity was 21. The 

 greatest mileage of wind in one hour was 46 on January 

 17th, when the velocity in gusts was at the rate of 64 miles 

 per hour. The total mileage of the horizontal component 

 of the wind during the year was 93,279, and the resultant 

 mileage 46,290 in the direction S. 67°.6 W. The rainfall is 

 slightly in excess of the average, and the snowfall very 

 decidedly so, being 55 inches above the normal and the 

 greatest, by 17 inches, for any one year on the records. 

 The rainfall in October, of which 4.06 inches fell during 28 

 hours, is the greatest recorded here during any one month 

 in the past eleven years. Although the amount of precipi- 

 tation measured in depth was above the average the num- 

 ber of days on which rain or snow fell was considerably 

 below the average. The year is thus marked as one of 

 heavy falls of both rain and snow. The amount of clouded 

 sky has been slightly less than usual, while there has been
