May 1.—The Lord Bishop of Norwich, President, in the Chair. 
John Hogg, Esq., F.L.S., exhibited a portion of a large and re- 
markable Wasp’s Nest, taken by himself last autumn, The portion 
exhibited formed about one-third of the entire nest, which was built 
in the inside of the roof of one of the wings of Mr. Hogg’s house at 
Norton in the county of Durham, a part being fixed under the roof, 
and the remainder to the side wall immediately below it. The hole 
under the slates by which the wasps went in and out was originally 
made by sparrows; and at this part, and among another portion of 
the wasp’s nest, appeared the remains of the old bird’s nest, con- 
sisting chiefly of straw with a few feathers. The entire wasp’s nest 
bore the appearance of having been the fabric of several years, some 
of it being apparently older and in inferior preservation to the rest, 
as well as somewhat blackened. Externally the nest is beautifully 
parti-coloured, the layers of the various substances used in the con- 
struction presenting circular or curved lines or rings, which are 
brown, buff, yellow, grey, dark grey, nearly black, &c.; altogether 
exhibiting a very elegant shell-like structure, which Mr. Hogg has 
not observed in any other British wasp’s nest. These layers he re- 
gards as indicative of the mode in which the wasps carried on their 
labours; one wasp, or set of wasps, having made use of the same 
substance (such as wood, lichen, the bark of a tree, &c.), collected 
from the same place, and of the same colour, to form one circular 
layer or ring ; and then having been succeeded by another wasp, or 
set of wasps, using other substances taken from another spot, and of 
a different colour; and so on. 
Mr. Hogg states that he has recently seen in the British Museum 
a very similar nest sent from China by Mr. Say; but the species of 
the Chinese wasp, or even its genus, is not stated. He had at first 
hoped that his nest might have proved the work of the new wasp
