On" Temperature and Vegetation in the Botanic 

 Garden, Glasgow, during December 1891. By Egbert 

 BuLLEN, Curator of the Garden. 



The weather throughout was exceedingly mihl, but mostly 

 very wet and stormy. 



The highest day reading on a shaded thermometer at 

 3 feet from the ground was 53°, on the 3rd ; the lowest 

 34°, on the 13th, when a light fall of snow was experienced. 

 The night readings were correspondingly high for the month ; 

 the lowest reading was 25°, or 7° of frost ; and the total 

 readings for the nine nights on which frost was registered 

 was only 31°. But on five or six other nights the mercury 

 was either at or very near the freezing-point. Within a 

 mile from the city the temperature was from 3° to 6° lower. 



The sudden change of wind and weather — frequent rains, 

 and thick fogs — were a great impediment to outdoor work.
