448] and likewise, for preserving those metals from the injurious effects of rust, we think it useful to add the following:

As experience proves, that the application of common oil, as well as that of paint, is but an imperfect security against the corrosive effects of air and moisture, we are informed, that articles manufactured of iron are not liable to be attacked by tlie rust, if this metal be previously poured into melted lead; then suffered gradually to cool; and this simple process be repeated several times.

Another mode of coating iron, with a view to prevent the formation of rust, is said to be obtained by the application of spermaceti, while the metal is hot: thus, a kind of bronze will be the result.—A more permanent varnish, however, is that of rubbing iron in a state nearly red-hot, with the horny hoofs of cattle, which are previously dipped in a small portion of oil: this process is asserted to afford the best defence from the destructive influence of air and humidity.  

 SCARBOROUGH WATER is obtained from two mineral springs which rise about a quarter of a mile from that town, in Yorkshire. One is a simple chalybeate water, similar to ; while the other, which is chiefly frequented, contains, in addition to the iron, a considerable portion of purgative salt.

The Scarborough-water may be advantageously used, in the various complaints for which is recommended: the former is, however, chiefly employed as an alterative; because few stomachs can support the large doses which are required to be taken, for producing a proper evacuation from the bowels.  SEA-PLANTAIN, or Plantago maritima, L. is an indigenous perennial, growing on the sea-coast, where it flowers in June or July.—This plant, when reduced to ashes, affords a considerable quantity of mineral alkali; which may be advantageously substituted for the , imported from Spain.  SLUGS, frequently harbour near the foundation of walls, and at the roots of pease, beans, lettuces, &c. where they commit great depredations. Mr., therefore, directs them to be picked off, and thrown into a vessel containing a little unslacked lime, which will inevitably destroy them: or, the ground infested by these vermin should be watered with a liquid, composed of soap-suds, urine, and a decoction of tobacco.

If slugs be uncommonly numerous on the surface of the ground, particularly in dewy mornings, or after rain, Mr. F. recommends fine unslacked lime to be scattered over the borders of the gardens, thus infested. He prefers, however, the preparation first mentioned; as it not only destroys the insects, but also prevents their increase, by killing their eggs, which are uniformly deposited in the earth.  SPICE.—Beside the utility of the Monarda, or Oswego-tea, as a substitute for spice, its leaves may be advantageously used instead of those
