 for the corresponding month last year. The lowest reading- 

 was 9°, or 23° of frost, which was registered on the 7th 

 of the month. (The same amount was registered on the 

 6th of January last year, and was the lowest reading 

 recorded last winter.) Other very low readings were 

 registered on the mornins-.s of the 6th and 8th, when the 

 glass fell to 13° and 15° respectively. The lowest day 

 temperature was 22° on the 6th, and the highest 58° on 

 the 14th. Of the forty selected plants whose dates of 

 flowering are annually recorded to the Society, the follow- 

 ing came into flower, viz.: — Bidhocodium vermim, on 12th
