-which are most striking about the middle of the month, when a 

 sharp rise from 28*95 on the loth to 29*70 inches on the 16th 

 occurred. The highest readings were on the 5th, 24:th, 25th, and 

 26th, when the pressure indicated was 30*30 inches. The lowest 

 reading was 28*95 on the 15th. 



As exemplifying the mildness of the weather which characterised 

 November it may be stated that that precocious plant, Jasminum 

 nudijloricm, Lindl., began to open its flowers at the beginning of the 

 month, several weeks earlier than usual. 



December. — The weather during this month was very varied in 

 character. Sharp touches of frost, heavy rains, northerly winds, 

 and an absence of sunshine, combined to make the atmospheric 

 conditions very trying and often disagreeable. 



During the first two weeks rains were intermittent and moderate 

 in quantity, but, after a week of dry frosty weather, heavy rain 

 fell on the 21th and daily thereafter until the end of the month. 

 The amount of rain which fell was 4*85 inches, of which 1*08 

 inches fell on the 30th. There were thirteen dry days. In 

 December, 1895, the rainfall was 4*49 inches, and there were 

 fifteen dry days. 



With the heavy rainfall and frequent frosts the temperature 

 was low. The average maximum was 40°, and the minimum 31°, 

 the former being the same as and the latter 1° lower than in the 

 corresponding month of 1895. The thermometer was at or below 

 freezing point on seventeen mornings, while the total amount 

 of frost registered amounted to 95°. The hardest frost occurred 

 on the 18th when 14° were registered. 



The barometric readings show a less erratic range of pressure 

 than what obtained in November. From 29*73 on the 1st the 

 pressure fell steadily to 28*65 inches on the 6th, after which it rose 

 steadily, after a heavy rainfall on the 7th, to 30 inches on the 20th 

 and 21st, which was the highest indicated for the month. There 

 were sharp changes during the stormy days of the last week, and 

 at the close of the year the atmospheric pressure was 29 '46 inches. 



Plants of the Christmas Rose {Hellehorus niger, Linn.) began 

 to open their flowers daring the first week and were in full bloom by 

 the 20tb, while Jasminum nudijlorum, Lindl., which had been 

 flowering early in November, was in full bloom during Christmas 

 week.
