very like what is figured by Baker in his work on the microscope. 
He had been unable to produce a specimen of Leaf-manna, Mr. 
Hanbury having informed him that he had never seen it. 
Specimens of the form of Grerman "Wallflower, known as var. 
gynantherus, were exhibited, in which the stamens are converted 
into carpels. 
A plant of Mrs. Pollock Pelargonium was shown, in which the 
greater portion of the plant had reverted to its parent Zonal. 
The Secretary had observed that the flowers in a similar instance 
were of diflerent tints. 
Mr. "Wilson Saunders sent specimens of Graya Sutlierlandi, to 
show that on the same plant some branches produced perfectly 
glabrous leaves, while on others the leaves were densely downy. 
He also sent a plant of Goleus Verscliaffelti, in which one shoot 
bore small contracted spoon-shaped leaves strongly cupped, and 
resembling in colour those of an Iresine rather than those of a 
Coleiis. Dr. Masters stated that some of the white-variegated 
Ivies constantly produced similarly shaped leaves. 
Mr. Parsons sent specimens of Azalea in which the flowers were 
singularly everted. 
Professor Westwood brought specimens of Mint deformed by 
jEcidmm MenthcB, a parasite which is often very injurious in 
Mint- and Peppermint-fields, which are also attacked by the Cop- 
per Web, a great pest occasionally to Asparagus-beds. He also 
alluded to the tuberiform organisms on the roots of Peas as occa- 
sionally serving for the food or resting-place of larvae. These 
organisms occur on various Leguminosas, and certainly do not 
depend on insect action. 
A gigantic Grourd, belonging apparently to the genus Luffa, was 
exhibited. 
Mr. Berkeley brought Peaches aftected with Oidium, which is 
apparently very prevalent this season. 
Dr. Hogg stated that those varieties of Peach and Nectarine 
which have glands on the petioles are comparatively free, while 
those without glands are very subject to mildew. The Noblesse, 
for instance, often sufters ; but a gland-bearing seedling of that 
variety often escapes. 
Dr. Hogg spoke of the plants in boxes under experiment at 
Chiswick as being in a state very favourable for observation. 
Mr. Grlaisher made some remarks on the meteorological obser-
