SIGNS AND SYMBOLS USED IN MEDICINE AND MUSIC.


SYMBOLS USED IN MEDICINE AND PHARMACY.

Scruple; i, one scruple; ij, two scruples; ss, half a scruple; iss, a scruple and a half.

Dram or drachm; i, one dram; ij, two drams; ss, half a dram; iss, a dram and a half.

Ounce; i, one ounce; ij, two ounces; ss, half an ounce; iss, an ounce and a half.

A minim; a drop.

(Gr. ana), of each a like quantity.

(L. recipe), take.

The above symbols are employed almost always in medical prescriptions. A prescription consists of the following parts: (1) The Superscription; (2) The Inscription; (3) The Subscription; (4) The Signature. The Superscription, which consists of the letter , is a relic of the days of astrology. It originally was used to represent the symbol of the planet Jupiter. By common consent it is now regarded as representing the imperative mood of the Latin verb recipere, to take. The Inscription is a statement of the names of the substances to be used, with their quantities. The Subscription is made up of the directions for the guidance of the dispenser. The Signature includes the directions to the patient. This part of the prescription should be written in English; the other parts are in Latin. Sometimes the signature also is in Latin.

The body or prescription contains the following: the Basis, or principal active ingredient; the Adjuvant, or Auxiliary, to assist its action; the Corrective, to correct or diminish some undesirable quality; the Vehicle, or Excipient, to give a suitable form for administration.
