PROMISOR. One who makes a promise.
2. The promisor is bound to fulfill his promise, unless when it is contrary to law, as a promise to steal or to commit an assault and battery; when the fulfillment is prevented by the act of God, as where one has agreed to teach another drawing and he loses his sight, so that he cannot teach it; when the promisee prevents the promisor from doing what he agreed to do; when the promisor has been discharged from his promise by the promisee, when the promise, has been made without a sufficient consideration; and, perhaps, in some other cases, the duties of the promisor are at an end.
