Truffles. —An immense stock of very small Truffles was discovered some 
years ago, under a young cedar tree, upon the lawn, near the House at Ilighelerc. 
Mr. Gowen successfully tried the experiment of transplanting several of these, 
and setting them under beech trees, marking the spots where they were planted. 
They increased in size, and became much finer than those which were left.—

Hatching Eggs by Steam. —As the hatching of Eggs by Steam seems to 
be a favourite mode amongst a peculiar class of Society connected with the fowl 
trade, the following table taken from different authors, by Count Morozzo, and 
given in a letter from him to Lacepede, may be interesting.

The Crane, and Heron, as well as the Ostrich, hatch their Eggs chiefly by the 
heat of the Sun. 
Window Swallow.— Two fine examples of immense masses of basalt are 
afforded on the hills of Penmaen Bach, and Peumaen Mawr. The cap or sum¬ 
mit of the latter, in appearance much resembles a volcanic crater. It is curious 
to observe, that the north-west front of this last hill is the favorite resort of mul¬ 
titudes of the common house swallow, whose clayey nests cover the rock in many 
places. —Field Nat. Mag.

The Meetings during the winter being confined to one in each month,that for November took 
place on the 5th. The only novelties observed were seedling Pine Apples, seedling Chrysan¬ 
themums, and flowers of Mimulus Smitliii, the new variety raised by Mr. Geo. Smith, of Is¬ 
lington. It is a powerful rival in beauty to the favourite M. rivularis and was much admired, 
as were also certain of the twelve sorts of Chrysanthemum exhibited by M. Wheeler, of Ox¬ 
ford, which will no doubt be regarded as agreeable changes from the Chinese sorts that have 
now been so long established in the estimation of the public. Mr. W.’s success has been con¬ 
siderable, and bis exertions were last season rewarded by a medal from the Society. The
