Professor Bayley Balfour exhibited specimens of Taphrina aurea, 

 received from ^Irs T. B. Sprague, and Exoascvs p'uni received 

 from Miss Hamilton Dalzell. 



Mr "\Y. B. Boyd of Faldonside exhibited a large series of alpine 

 and other plants which were then flowering in his garden. 



Dr W. Craig exhibited a finely fasciated stem of lily. 



During the session Mr Bullen, Curator, made the following 

 reports on temperature and vegetation at the Glasgow Botanic 

 Garden : — 



October. — A few very fine days have been recorded, but the 

 majority have been sunless, with frequent rain, occasionally heavy. 

 If we except the twelve nights on which the thermometer fell to or 

 below the freezing-point, the temperature, both day and night, has 

 been above the average. The lowest night reading was 26°, on 

 the night of the 28th. Total frost, 18°, and three times at freez- 

 ing-point. During one-half of the month the maximum day 

 temperature in the shade varied from 50° to .55°. The lowest day 

 reading was 41°, on the 26th. Single Dahlias were blooming 

 freely up to the night of the 28th. Late-blooming perennials have 

 been earlier and better developed than is usual in our climate. 

 Many of the more tender annuals never recovered the muggy 

 weather experienced for several successive days last month. 



Comparatively few hardy plants have ripened seed satisfactorily, 

 the latter part of the season being less propitious than the early 

 part. 



November. — The mean temperature has been high for the 

 month, considering that frost was registered on eleven nights. Of 

 the 49° recorded as the total for the month, no less than 30° were 

 registered on the nights of the 25th, 26th, and 27th; 19°, or 13° 

 of frost, being the lowest reading during the night of the 26th. 

 The day temperature was invariably high, the only low reading 

 being 31° on the 26th, and after a light fall of snow. This cold 

 wave came quite opportunely, for the buds of most hardy plants 

 were far advanced for the season. It has been a splendid season 

 for outdoor garden work. 



December 1889. — This has been a comparatively mild month, 

 for although the thermometer has been at or below the freezing 

 point on nineteen nights, the mean readings have been high
