The act of prescribing, directing, or dictating; direction; precept; also, that which is prescribed. 2. (Med.) A direction of a remedy or of remedies for a disease, and the manner of using them; a medical recipe; also, a prescribed remedy. 3.

That profound reverence for law and prescription which has long been characteristic of Englishmen. --Macaulay. Note: Prescription differs from custom, which is a local usage, while prescription is personal, annexed to the person only. Prescription only extends to incorporeal rights, such as aright of way, or of common. What the law gives of common rights is not the subject of prescription. Blackstone. Cruise. Kent. In Scotch law, prescription is employed in the sense in which limitation is used in England and America, namely, to express that operation of the lapse of time by which obligations are extinguished or title protected. Sir T. Craig. Erskine.
