rROCEEDINGS OF SOCIETIES. 
HORTICULTURAL SOCIETY. 
March 21.—Some fine specimens Ixora coccinea^ Berberis aquifolium^ Den- 
drobiimi aggregatum^ Euphorbia jacquinifiora^ Nemophila insignis, &c., were ex¬ 
hibited. Amongst the varieties of the Apple was noticed the Melo di Carlo^ or 
Finale Apple, so highly esteemed in Italy, but which cannot be successfully 
cultivated in this country; at least the attempts which have hitherto been made 
have failed. 
The exhibitions, at the Society’s gardens, for the present year, will take place 
on May 13, June 10, and July 8. 
ENTOMOLOGICAL SOCIETY. 
April 3.—The Rev. F. W. Hope, F. R. S., in the chair.—Some specimens of 
exotic insects were exhibited by Lord Prudhoe ; amongst others, the queen of 
the workers of the White Ant.—The Secretary then alluded to the condition of 
some of the pictures in the National Gallery, which have been much injured by 
insects, and read an extract from the Parliamentary Reports upon the subject. 
Several members rose to suggest remedies for the extermination of these little 
pests, and we certainly think it would be both interesting and useful to make 
trial of some of them. The Secretary further cautioned agriculturists against the 
employment of a powder recently advertised, and which professes to prevent the 
Turnip-seed from being attacked by “ the Fly,” and which, from the recent dis¬ 
coveries relative to the habits of that insect, is entirely inefficaceous.—Mr. Raddon 
exhibited some lepidopterous larvee, found in considerable numbers in a Wheat- 
stack near Bristol, in which they had caused much damage, by devouring the 
grain.—A paper was read ‘‘ On the economy of one of the species of the family 
CynipidiE^ residing in the flat circular galls on the under side of Oak leaves,’* 
and which have been mistaken for Fungi. Also, “ On insects and the larvso of 
insects found in the human body,” by the Chairman, illustrated by figures of 
species obtained from the human body, and by a series of tables, to elucidate the 
different cases of scolechiasis, canthariasis, and myasis. This paper was the sub¬ 
ject of an interesting discussion, by the author, Messrs. Bell, Owen, Bracy 
Clark, Hr. Blundell, and others.—Nor ought we to pass unnoticed the dona¬ 
tions of books and insects to the society’s collection, the latter including specimens 
of the beautiful Chiasognathus Grantii^ from Cheloe, the gift of C. Darwin, Esq. 
GEOLOGICAL SOCIETY. 
March 22. — The Rev. W. Whewell, Pres., in the chair.—The commence¬ 
ment of a paper was read by Mr. Roy, ‘‘ On the supposed ancient state of the 
North American Continent, especially on the extent of an inland sea, by which a
