_Zoological Society_.

A catalogue of the members has been published, which includes 1,291
names, besides corresponding members. The museum in Bruton Street has
received, and is daily receiving, valuable additions, as is the garden
in the Regent's Park. The extent of this garden has been, in consequence
of the various donations and purchases, considerably increased, and
several neat and appropriate structures are now erecting for the abode
of different specimens. It is a gratifying circumstance that these
specimens are, for the most part, clearly and distinctly named, with
the native country of the animal added. We could wish to see a greater
variety of trees, shrubs, and herbaceous plants introduced, and equally
clear names and geographical indications placed at them also. Why
should it not, as far as practicable, be a botanic garden as well
as a zoological garden?--_Ibid_.

_Galvanism_.

Mr. Becquerel has discovered that the temperature of a conducting wire
communicating with the two poles of a pile, increases from each of its
extremities, and constantly reaches its maximum in the middle of the
wire.--_Brewster's Journal._

_Alloyed Iron Plate_.

A manufacture of prepared iron has been practised, and the substance
produced used to a considerable degree in Paris. This has been to
prepare iron in large plates, and other forms, so that it will not rust.
This has been effected by coating it with an alloy of tin and much lead,
so as to form an imitation of tin plate. Trials have been made, and
proved favourable; it resists the action of certain fluids that would
rapidly corrode iron alone; it can be prepared of any size, and at a
low price. Its use in the manufacture of sugarpans and boilers, in the
construction of roofs and gutters, is expected to be very considerable.

_Saline Lake of Loonar in Berar._

This curious lake is contained in a sort of cauldron of rocks amidst
a pleasing landscape, and is of course the object of superstition. The
taste of the water is uncommonly brackish. Mr. Alexander, who describes
it, found by a rough analysis that 100 parts contain

Muriate of Soda 20 parts,
Muriate of Lime 10 parts,
Muriate of Magnesia 6 parts,

The principal purpose to which the sediment of the water is applied is
cleansing the shawls of Cachmere. It i
