The following paper was read : — 



On Temperatuke and Vegetation at the Eoyal Botanic 

 Garden, Edinburgh, during the month of June 1893. By 

 Egbert Lindsay, Curator of the Garden. 



The past month of June was remarkable for the excessive 

 heat and dryness which prevailed. The continued want of 

 rain having lasted throughout nearly the whole of the past 

 spring, the marvel is that its effects have not been more 

 serious on vegetation. The lowest reading of the thermometer 

 during June was 40°, which was registered on the 2nd; on 

 the night of the 16th the thermometer did not fall below 

 62°. The lowest day temperature was 50°, on the 23rd, 

 and the highest 89°, on the 18th of the month. Hardy 

 herbaceous plants flowered freely, but went quickly past 

 owing to the drought ; the earlier flowering kinds have 

 ripened their seeds abundantly.
