Art. IX. — Meteoeology 1873, Halifax, N. S. By Feed. 

 Allison, M. A., Chief Meteorological Agent. 



Having already in another paper this season, laid before the 

 Institute the progress of "Weather Telegraphy and Storm Warnings 

 in Canada, in this communication I merely rehearse the results of 

 observations at Halifax in 1873, taking them up where dropped in 

 December 1872. The succeeding January opened with a high and 

 ascending Barometer, which was generally maintained. After the 

 snow fall of the last night of the past year, the Temperature fell 

 considerably, giving a clear and cold New Year, with excellent 

 sleighing. The month was not, however, very cold ; its mean 

 Temperature being 23.°59 or .56 above the corrected mean of 

 January for eleven years. N. W. wind, as usual, preponderated, 

 with but little velocity. The total precipitation, 7.83 inches, was 

 very large. Bain and snow both exceeding, but especially the 

 latter. We had 3 auroras, 2 fogs, and miscellaneous phenomena 

 not numerous. But once the wind reached a gale on the morning 

 of 28th, accompanied with six inches of snow. Heavy sleet and 

 snow were falling the previous evening. At night the wind backed 

 from S. E. to N. N. W., and snow increased in the morning till 

 8h. 15m. when it ceased. Thunder and lightning at 4 a. At 6h. 

 30m. a wind blowing 3S miles per hour, and then fell. The 

 following day grew very cold, and at 7h. 30m. a. of 30th Tempera- 

 1;ure was 14. °4 below zero — the minimum since 7th January, 1866. 



February showed a marked decrease of pressure, and somewhat 

 below its own normal. It was steadily cold 2.°80 below the 

 mean of February, and being nearly 3° colder than the preceding 

 January — an unusual occurrence — there being in a long series but 

 very little difference between these two months, and January on 

 the whole the coldest. Prevalent wind N. W. A noticeable 

 • decrease in rain and snow took place — only 0.49 of an inch of the 

 former being measured, and 10.7 inches of the latter; so that the 

 month was a fine one, though very cold. Two gales took place ; 

 neither very heavy. The 8th began with sleet, then heavy rain, 

 and S. E. gale in morning. A shower in the forenoon. Fog at
