Remarks. 



On the whole the weather throughout this month was 

 favourable for the operations of the Garden, especially 

 during the first three weeks. On the 22nd, the frost 

 set in suddenly, and continued very severe for about a 

 week, during which time the minimum temperature in the 

 shade was as low as io°, the cold being as intense as at 

 any period of the continued frost of last winter. On the 

 24th however the snow covered the ground before the 

 frost had penetrated to any great great depth, and the 

 roots of plants were in consequence less injured than they 

 otherwise would have been. It will be observed, that on 

 the night of the 24th, the radiating Thermometer instead 

 of being lower, was 6° higher than the min. temp, in the 

 shade, which is accounted for by its being covered by the 



Mean Pressure from the 3 daily observations 2^.646 inches.
