The destructive effects on vegetation which resulted from the 

 intense frost that occurred in this month have beenjspecially de- 

 tailed at p. 225, and to the numerous facts there recorded, fu- 

 ture reference may be readily made. The greatest degree of 

 intensity was attained on the night between the 19th and 20th. 

 the registering thermometer indicating 4 £° below zero, whilst 

 the index of the one exposed in a concave metallic speculum 

 receded to iz° below zero. The mean temperature of the month 

 was about 8£° below the average of 10 preceding years. The 

 weather was previously very mild, and this circumstance, to- 

 gether with that of the ground being almost free from snow, 

 appear to have been the causes of much greater destruction 

 among plants than would have otherwise occurred.
