In English law. The name of a writ formerly used to recover the amount of a judgment from an executor. Scire leges non hoc est verba earum tenere, sed vim ac potestatem. To kuow the laws is not to observe their mere words, but their force aud power; Ithat is, the es- sential meaning in which their efficacy resides.] Dig. 1, 3, 17; 1 Kent Comm. 402. Scire propria est rem ratione et per causam cognoscere. To know properly is to know a thing in its reason, and by its cause. We are truly said to know anything, where we know the true cause thereof. Co. Litt 1836.
