also on the table. Under a binocular microscope, brought by the Rev. W. 
Bramley-Moore, were exhibited some young trout, lately hatched, in which 
the circulation was shown. The President exhibited, among other objects, 
the beautiful stellate hairs of Alysswm spinosum, and other plants; the 
Two-wheeled Rotifer (2. vulgaris); the feather of a Humming-bird, etc. 
The meeting, which was very numerously attended, did not break up until 
nearly 10 p.m. 
SixtH Eventne MEETING, MArcH 19.—Held at the house of the 
President, at his kind invitation. The Rey. W. Hunt Painter, who had 
promised to read a paper, was unavoidably prevented from attending ; and 
the only paper read was one by T. Marshall, Esq., “On the Migration of 
Birds,” being an extension of one previously delivered: on this occasion 
the winter migrants were chiefly referred to. The President gave an 
interesting Geological lecture, chiefly explanatory of the fossils on the 
table, which he had brought from the Isle of Portland, Weymouth, etc. 
Some very beautiful living Sea-Anemones, from the same locality, were 
much admired. The Secretary exhibited a specimen of Daphne Mezereum, 
from the newly-discovered locality near Walter’s Ash. The meeting 
terminated with an exhibition of the microscope. 
Correspondence, 
We shall be glad to receive articles on any natural objects, the preference 
being always given to such as have a local interest. Notes on the popular 
names of, or traditions concerning, Animals or Plants, or on any subject con- 
nected with Natural History, wili be welcome. 
Scarcity oF Common LEPIDOP- 
TERA (see p. 170).—In the January 
number a correspondent, writing of 
the scarcity of Lepidoptera in the 
neighbourhood during the last 
season, invites observations from 
other localities. In this neighbour- 
hood the small number seen was 
equally remarkable. I saw a few 
fine specimens of the Brimstone 
Butterfly (G@. Rhamni), in the skirts 
of the Fawley Woods, and the 
Speckled Wood (ZL. -Ayeria) was 
plentiful as ever in every wood and 
copse aroundus. Later, the some- 
what rare Painted Lady (C. Cardui) 
appeated in greater numbers than I 
have seen for some years, and I 
covld have secuied fitie specimens 
in the lanes and hedgerows. Of 
others, usually more generally dis- 
tributed, the falling off was very 
noticeable. I have no doubt the 
cause was attributable to the un- 
genial spring.

I see in the Correspondence pages 
a notice of the scarcity of common 
Lepidoptera last year. In September 
a friend wrote me from Hounslow 
that during his fortnight’s holiday 
there he had scarcely taken any- 
thing : one Clouded Yellow, and two 
or three Small Tortoiseshells were, I 
believe, all, though, unfortunately, 
I have not preserved the letter. In 
July, however, I did not notice any 
scarcity at home (Fowlness, Essex), 
there being the usual numbers of 
Urtice and Atalanta, also Janira,
