Berwick, Roxburgh, Aberdeen, and Inverness-shires, it had gone down several 

 degrees below it. Thus, Mr. Loney, Marchmont, Dunse, reports that on 

 June 10 he registered 9» of frost on the ground with the black bulb ther- 

 mometer, and 3^ at 4 feet above the aurface. Young Potato plants and 

 young foliage were blackened. The lowest readings at the Royal Botanic 

 Garden were as follows: — On the 6th, 380; 7th, 35»; 8th, 37» ; 9th, 340; 

 lOth, 380; 16, 380; 24th, 360; 28th, 38». These low temperatures greatly 

 checked the growth of Vegetation and the fertUising of the flower. 



Since July commenced the night temperatures on an average have been 

 higher, the four lowest being, on the Ist, 40»; 2d, 44«; 7th, 450; 9th, 45o. 



During the past six weeks the effects of last winter on Vegetation have 

 become very marked. Many plants that produced young shoots in spring, 

 and gave promise of continued growth, have succumbed, while many more 

 threaten to follow them next season. Since the last meeting 162 species of 

 plants have come into flower on the rock garden, making for the season 

 over 500 species and varieties. Mr. S a d 1 e r read, amongst others, the report 

 he had received from Mr. Davidson of the Palace Garden, Hamilton. 



Mr. Alexander Bncbau called attention to the striking parallels of 

 temperature betwixt this Hamilton district and that around Edinburgh. He 

 accounted for it by a similarity in features of physical geography.
