A written confession of faith; a formal statement of foctrines. 3. <mathematics> A rule or principle expressed in algebraic language; as, the binominal formula. 4. <medicine> A prescription or recipe for the preparation of a medicinal compound. 5. <chemistry> A symbolic expression (by means of letters, figures, etc) of the constituents or constitution of a compound. Chemical formulae consist of the abbreviations of the names of the elements, with a small figure at the lower right hand, to denote the number of atoms of each element contained. <chemistry> Empirical formula, a formula indicating the supposed molecular constitution of a compound.
