rather, there will scarcely be a definite season of vernal intermittent, but the remittent will commence immediately, increasing in extent and severity as the summer advances, and promising to become, in the autumn, the greatest season of disease that England has known for this century. Dr. Macculloch attributes this alarming increase to _malaria_, on the production and propagation of which he has recently published an essay, the leading argument of which is, "that as the quantity of the poison which any person can inspire is necessarily small, and as this small quantity can be produced by a small marshy spot as well as a large one, it is the same, as to the production of the disease, whether the marsh is a foot square or a mile, provided the exposure be complete; while also any piece of ground where vegetables decompose under the action of water is virtually a marsh, or must produce _malaria_." _Acclimatizing Plants_. A Mr. Street, of Biel, in East Lothian, has recently made some successful attempts at acclimatizing, or giving to exotic plants greater powers of withstanding cold than they had when first introduced. By planting in situations well drained from superfluous moisture, under circumstances where rapid growth was rendered impracticable, and in a garden admirably adapted to the object from its position, he has succeeded in naturalizing, in latitude 56 deg. 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 deg. and never lower than 54 deg. of Fahrenheit. _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 of a brush, and then be wiped; this gives a slight grey tint to the surface, and causes the ready adhesion of the verdigris, &c. The second solution is then to be rubbed over by means of a brush, until they have acquired the deep red colour of copper; they are then to be left an hour to dry, after which they are to be polished with a very soft brush and rouge, or the red oxide of iron in fine powder. The polish is to be completed by the brush alone, the medals being passed now and then over the palm of the hand.--_Verly_. _Culture of Celery_.
