PROCEEDINGS OF THE SOCIETY. 
that the drawings made upon the black-board sufficiently convinced 
him, without looking further at the specimens, that the plant which they 
had there was one which was common on almost all the hard-leaved 
shrubs, Capnodium Footii. It was the early condition of it, and be- 
yond which it seldom proceeded farther in this country. It consisted 
chiefly of a pellicle of mycelium, the free cells of which gave rise to 
the quantity of threads shown. In the fourth volume of the Journal 
of the Horticultural Society they would find a paper upon the subject 
by the Rev. J. M. Berkeley and Desmazieres, in whicli it was fully 
described, and which, he believed, gave rise to the genus Capnodium, 
which at present contained three species, of which this one, C. Footii, 
was the most common. With reference to the pellicle being so easily 
removed, he had the honour of reading a paper before the Royal 
Horticultural Society upon this subject, and the conclusion at which 
he then arrived was that in many cases it appeared that this fungus 
developed itself upon the honey dew and other secretions upon the 
surface of the leaf. For instance, the lime tree was well known for 
the quantity of sweet matter found upon its leaves, and in the autumn 
it was not unusual to find almost every leaf affected by a black, sooty 
appearance, which was nothing more nor less than Capnodium, and it 
appeared certain tliat this fungus drew its nutriment from this secre- 
tion of saccharine matter either by some of the Aphis tribe or by 
the plant itself, without striking at all into the substance of the leaf. 
The President felt sure they were all very much obliged to Dr. 
Cooke for the very interesting remarks which he had made. It 
showed that if the Fellows of the Society would sometimes mention 
things which came under their notice, it might, as in the present 
instance, lead to a very interesting communication from some one 
present who might be qualified to give them the further information 
which they required. 
The following gentlemen were elected Fellows of the Society : — 
Mr. Amos Hobson ; Mr. George Brook ; Mr. G. A. Woods ; and 
Mr. Frank Campion. 
Scientific Evening, May 15 , 1878 . 
The last scientific evening of the session was held, by kind per- 
mission of the authorities, in the libraries of King’s College, on the 
15th of May. There was a good attendance of the Fellows, and as 
the subjoined list will show, apparatus and objects of great interest 
were exhibited. The Society were indebted to Messrs. How and Co. 
and Mr. Baker for the use of a number of excellent lamps.
