_Acclimatizing Plants_.

garden admirably adapted to the object from its position, he has
succeeded in naturalizing, in latitude 56° N. plants which have not yet
been known to endure the winters even of the parallel of
London.--_Quarterly Journal of Science_.

In a table kept at Sydney by Major Goulburn, from May 1821 to April
1822, the thermometer never rose above 751/2° and never lower than 54° of

_Bronzing Tin_.

To obtain complete success in bronzing medals of tin, the two following
solutions must be employed:--

The first, which is merely a wash, is composed of 1 part of iron, 1 part
of sulphate of copper, and 20 parts, by weight, of distilled water. The
second solution, or bronze, is composed of 4 parts of verdigris and 16
parts of white vinegar. The medals should be filed, and well cleaned
with a brush, earth, and water; and being well wiped, should have a
portion of the first solution passed slightly over their faces, by means
