the Earth of Malta: an earth of which there are two very different kinds; the one of which is a loam, the other a marl. The latter is that known by medical authors under this name; the former is the Malta earth now in use; but both being brought from the same place, are confusedly cal- led by the same name. The Maltese marl, which is the terra Melitensis of medical authors, is a loamy, crumbly, and light earth, of unequal and irregular texture; and, when exposed to the weather, soon falls into fine soft powder: but when preserved and dried, it becomes a loamy, light mass, of a dirty white colour, with a greyish cast; it is rough to the touch, adheres firmly to the tongue, is very easily crumbled to pow- der between the fingers, and stains the hands. Thrown into the water, it swells, and afterwards moulders a- way into a fine powder. It ferments very violently with acids. Both kinds are found in great abundance in the island of Malta, and the latter has been much esteemed as a remedy against the bites of venomous animals. The other has supplied its place in the Ger- man shops; and is used there as a cordial, sudorific, and astringent.
