ROYAL HORTICULTURAL SOCIETY. 
Mr. Andrew Murray showed specimens to prove that Dr. 
Eoberts's method of treating trees affected with Scohjtus could do 
little to repair their already diseased condition. Courval's plan 
of dressing the trees after pruning equally failed to produce any 
true union between the old wood and the new. 
Mr. McLachlan said that it was only trees which were already 
diseased which were attacked by the Scolytus; the insect, in fact, 
had no chance except in a feeble tree. Mr. "Wallace and Mr. Eates 
equally failed to find wood-eating beetles in the native forests ; 
they were only met with where clearings were being made. 
GEJN'EEAL MEETIIS^G. 
W. W. Saundees, Esq., E.E.S., in the Chair. 
Mr. Berkeley brought a flowering plant of Lupinus rivularis, raised 
from seeds gathered on the banks of the Dee below Ballater, where 
it is perfectly naturalised. He then alluded to a case of disease 
in the Yine, which attacked the nodes, causing them to break off, 
and which ha thought was duo to excessively wet weather, in 
which he was confirmed by Mr. Barron.
