This was perhaps the coldest April ever remembered. The 

 mean temperature was certainly lower than that of any corres- 

 ponding month for at least the last 40 years, being only about 

 42 0 Fahr., which was nearly 7 0 lower than the average of April 

 for the 10 preceding years. During the first three weeks, the 

 wind was almost constantly from the North or North-East, and 

 exceedingly cold and dry for the period of the season. A hazy 

 state of the atmosphere prevented the Sun's rays from reaching 

 the earth, whilst the wind was from the points above mentioned, 

 and when it changed, after the 20th, the weather was generally 

 cloudy and wet. Most kinds of foliage under glass were evi- 

 dently assuming a yellow tinge. Vegetation in the open air 

 made no efficient progress. The common Lilac was a month 

 later than usual in coming into leaf, and its buds remained in a 

 half expanded state from the beginning till the end of the month. 

 Mean Pressure from the 3 daily observations 29.811 inches. Fahr.
