The following Communications were read : — 



I. Opening Address on the Ocenrrence and Formation, as 'well 

 as the Chemical and Physical Characteristics of Chlorophyll. 

 By Professor Bayley Balfour, President. 



II. On the Progress of Vegetation at the Royal Botanic Garden 

 during November. By Mr John Sadler, Curator. 



Mr Dunn, Dalkeith Palace, said it was remarkable that, with so 

 much open weather, there had been so little growth of vegetation 

 of any kind. 



Mr Buchan stated that meteorological records for 118 years 

 back showed that the temperature for last month over the British 

 Islands had been very greatly above the November of any recorded 

 year. This was particxdarly the case in the upper parts of the 

 valleys of the Tweed and Clyde, and of the Trent and Thames, 

 where the temperature was 6° to 7° above the average of previous 

 Novembers. Going back on the whole 118 years, last November 

 was the warmest November in those restricted parts, and over the 

 rest of Great Britain it was nearly the warmest. Sir Kobert Christi 

 son had a weather prognostication, that if there was sufficient frost 

 to harden the ground in the last week of October or the first week 

 of November, the coming winter would be mdd, and so far that had 

 turned out to be correct. 



MISCELLANEOUS COMMUNICATIONS. 



1. Mr John Campbell, Ledaig, Argyleshire, sent Escallonia 

 macrantha and Rhododendron Nohleanum in bloom from his garden, 

 the greater part of which had been washed away by the great gale 

 of November. 



2. Sir Eobert Christison, Bart., exhibited twigs with fruit from a 

 vigorous oak tree about 170 years old, and 10 feet in girth of trunk 

 at narrowest, being one of several in an avenue in Dalswinton Park, 

 Nithsdale, 1880; also twigs with acorns from several natural oak 

 trees at or near Ballahulish, August 1880.
