The effects of frost, canker, aphis, fungus, &c., were alluded to, 
but no definite conclusion was arrived at as to the real cause of 
the disease. 
Action of Carbolic Acid on Plants. —Mr. MacLachlan alluded to 
some experiments of Miss E. Ormerod on the action of “ Sub- 
Phenyl ” in killing the larvse of Psila rosse, the Carrot-fly, which 
feeds on Carrots. Not only were the larvae destroyed, but the 
growth of the plant, so far as foliage was concerned, was much 
promoted. 
Nomenclature of Garden Plants. —Dr. Masters read a paper on 
this subject, pointing out the chief difficulties and sources of 
confusion, botanical as well as horticultural, and suggesting 
certain means of remedying the evils, as by the construction of 
an authoritative standard catalogue of garden plants; by proper 
supervision and control exercised by the Scientific, Fruit, and 
Floral Committees respectively, &c.
