" Clognini, an Italian physician, ordered two or three drachms of crude mercury to be worn as a defensive against the jaundice; and also as a preservative against the noxious vapours of inclement seasons: "It breaks," he observes, "and conquers the different figured seeds of pestilential distempers floating in the air; or else, mixing with the air, kills them where hatched."

For very small Toy dogs, such as Italian Greyhounds, Yorkshire Terriers, etc., I should not recommend even oil itself, but mannaone drachm to two drachms dissolved in milk.

It should be exhibited in doses of one to two drachms in a little warm milk; or if it cause flatulence in this form, in some aromatic water, a desert spoonful of carraway-seed or dill water.
