ALLISON — ON THE METEOROLOGY OF HALIFAX. 81 



scanty, and winds strong from the usual north west quarter. The 

 total precipitation was very large ; the rain fall more than supplying 

 the deficiency of snow. We had no fog, five auroras, five hoar 

 frosts, three lunar halos, four gales, and but five days sleighing. 

 The strong east gales at the close of this month have also been fully 

 mentioned last year. 



February came nearer the normal temperature. Its whole pres- 

 sure was very light. I must again refer to last year's paper for 

 notable barometrical disturbances in this month. Cloud far ex- 

 ceeded that of January, and its own average ; prevalent north 

 west wind strong ; great precipitation, being nearly double the 

 average amount, especially large in rain. There was but one fog, 

 two auroras, and three hoar frosts, two lunar and one solar halo ; 

 three gales were felt : that of 9th morning was strong from east, 

 and blew again at night from west. There was sleighing nearly all 

 February, from beginning to 25th. 



The following month, March, was very similar in general tem- 

 perature, but the minimum of the year occurred on the 12th of 

 March. Pressure of the atmosphere still extremely small, with a 

 range rather limited for the season, and not much force of vapour. 

 For this month also some barometrical notes are contained in Pro- 

 ceedings of this Institute for 1870. The brightness of the ap- 

 proaching spring was well defined in March, when cloud was in de- 

 cided defect. Prevalent w^nd direction, N. N. A¥., and mean 

 force great. A decrease in rain and snow fall, but chiefly in former, 

 left total of the two not much above two thirds of average. Wild 

 geese passed on 19th, peach blossomed 24th, and wild pansies 28th. 

 Again one fog, and the large number of eight auroras ; five hoar- 

 frosts were noted, two lunar halos, three gales were felt — counting- 

 those of 17th and 18th as two, — all more or less eastwardly ; we- 

 had eleven days of sleighing ; robins reappeared 30th. 



April temperature returned to a figure much above the normal. 

 The minimum was high, 22^.6, and the maximum 66°. 4. The 

 pressure mean 29.743, was but .001 below an eight years average ; 

 and the monthly percentage of relative humidity, 86.1, the greatest 

 in 1870, cloud still remains deficient. The prevalent wind was 

 E. S. E., a peculiar direction, and small force. Total preci-
