EMISSION, med. jur. The act by which any matter whatever is thrown from the body; thus it is usual to say, emission of urine, emission of semen, &c. 2. In cases of rape, when the fact of penetration is proved, it may be left to the jury whether emission did or did not take place. Proof of emission would perhaps be held to be evidence of penetration.
