 to take part in the proceedings on June i and 2, 1899, to

 Lucasian Professor of Mathematics, the Council has nominated

 represent the Society on the occasion. 



The Council has awarded : — 



The Wilde Medal for 1899 to Sir Edward Frankland, K.C.B.,

 researches in pure and applied chemistry ; 



The Wilde Premium for 1899 to Mr. Charles H. Lees,

 ductivity, communicated to the Society. 



Professor William Ramsay, F.R.S., was appointed to deliver

 Lecture was delivered on Tuesday, February 28th, 1899. 



By the death of Ferdinand Julius Cohn on the 25 th of June, 

 1899, the Society lost a most distinguished honorary member. 

 Born in Breslau in 1828 Cohn, after studying both in his native 

 town and at the University of Berlin, became Privatdocent in 

 Breslau in 1856, Extraordinarius in 1859 and ordinary Pro- 

 fessor in 1872. But though his life was thus confined to the 

 Silesian capital, his name and his work were familiar to all 

 botanists. His tastes inclined him particularly to the study of 

 minute organisms, chiefly algae and fungi, and his investigations 

 on these two groups of plants led to the publication of his very 

 important " Beitraege zur Biologie der Pflanzen " commenced in 

 1870 and brought to a conclusion in 1896. Besides numerous 

 separate memoirs on various cryptogamic plants he was also 

 responsible for the " Kryptogamen Flora von Schlesien "
