On Temperature Vegetation, in the Botanic Garden, 

 Glasgow, during May 1891. By Egbert Bullen, Curator 

 of the Garden. 



This was for the most part a very cold month, and strong 

 easterly winds were frequent. A considerable cyclone passed 

 over this district on the 14th, after which the weather gener- 

 ally was more like March of an ordinary season. Snow was 

 frequently to be seen falling lightly, and the sun shining at 

 the same time, while thunder-showers and hail were frequent. 

 On the 10th, and again on the 12th, the temperature was 

 hio;h. On the latter date, 73° was registered on a shaded 

 thermometer at 3 feet from the ground, which is very 

 unusual at this season. Light morning frosts were frequent 

 here, but in some districts not far removed, as much as 

 8° were registered, the early bloom of fruit trees being 

 destroyed ; while in later districts, and where bloom is also 

 abundant, there is yet hope. 



Most out-door plants are in such a backward state, flowers 

 for teaching purposes cannot be had at the usual time.
