III. On Temperatures from 1st January at Royal Botanic 

 Garden, and Effects thereof on Vegetation. By Mr John 

 Sadler, Curator. 



Mr Johnston mentioned that on January 14th, in various districts 

 from Perth to Coupar-Angus and all through Strathmore, the 

 thermometer had registered from 3° to 5° and even 7° below zero. 

 So severe had the frost been that large branches of Portugal laurels, 

 6 inches in diameter, had been split open by the subsequent ex- 

 pansion of the sap.
