The oil may be given in capsules, or in the form of an emulsion, with or without maltextract, or success may be obtained by adding, to every two drachms of the oil, ten minims of pure ether and a drop of peppermint oil.
The usual dose, at starting, is one or two drachms, but the oil should be given eventually in the largest quantities that the patient can tolerate.
At Corinth the unit was evidently the Assyrian and not the Attic, being 129.6 at the earliest (17) (though modified to double Attic, or 133, later) and being divided by 3, and not into 2 drachms. And this agrees with the mina being repeatedly found at Corcyra, and with the same standard passing to the Italian coinage (17) similar in weight, and in division into 1/3 -- the heaviest coinages (17) down to 400 B.C. (Terina, Velia, Sybaris, Posidonia, Metapontum, Tarentum, &c.) being none over 126, while later on many were adjusted to the Attic, and rose to 134.
Troy or apothecaries' weight, +0.2 grain is allowed; on 1 pint pot, 4 fluid drachms is permitted; on 1 brass yard, 0.05 inch in excess or 0.02 inch in deficiency in length is allowed for ordinary trade purposes.
The pharmacopeial tincture may be given in doses of five to fifteen minims, and the infusion has the unusually small dose of two to four drachms - the dose of other infusions being an ounce or more.
