ing again heated before they are used, and though it is
to be regretted that persons should be reduced to such food, yet they
are cheaper and more wholesome than the bread usually given in times
of scarcity to the poorer classes.
_New Pyrometer_.
A new air-thermometer has been invented by M. Pouillet, for the
purpose of measuring degrees of heat in very high temperatures; an
object hitherto of very difficult attainment. By means of this
instrument it has been ascertained, that the heat of melted silver is
1677 deg.; of a melted mixture of one part gold and three parts silver,
1803 deg.; and of melted pure gold 2096 deg..
_To Destroy Slugs_.
A correspondent of the _Gardener's Magazine_ states, that after in
vain trying salt, lime, and dibbling holes for preserving young
cauliflowers and cabbages from slugs, he succeeded by spreading some
well cut chaff round the plants under hand glasses, and some round the
outsides of the glasses. The slugs in their attempt to reach the
plant, find themselves immediately enveloped in the chaff, which
prevents their moving, so that when he raised the glasses to give the
plants air, he found hundreds of disabled slugs round the outside of
the glasses, which he took away and destroyed.
_To make Kitchen Vegetables tender_.
When peas, French beans, &c. do not boil easily, it has usually been
imputed to the coolness of the season, or to the rains. This popular
notion is erroneous. The difficulty of boiling them soft arises from
an excess of gypsum imbibed during their growth. To correct this,
throw a small quantity of subcarbonate of soda into the pot along with
the vegetables.--_From the French_.
_Beet Root Sugar_
Has now become an article of some practical magnitude in French
commerce; since the annual consumption is between seven and eight
million pounds.
_Silk Trade_.
It was lately mentioned by Mr. Huskisson, in the House of Commons, as
a proof of the flourishing state of our trade, that British Bandanna
handkerchiefs were in the course of shipment to India. In addition to
this fact, we can state of our own knowledge that they are now
exporting to France, in no inconsiderable quantities, not merely as
samples, but in the regular course of trade.--_For. Quart. Rev._
_Electricity_.
It is curious to take a retrospective view of the mode in which the
effects of the Leyden phial were announced to the world, on their
first discovery. The ph
