¶4It is not ordinarily the function of an appellate court to review and pass on questions of the admissibility of evidence in an ongoing trial. This is a function of the trial court. The appellate court is seldom in as good a position as the trial court, which has monitored the entire flow of evidence in a case, to make isolated eviden-tiary rulings during a trial in progress. The appellate court will exercise its supervisory jurisdiction in such matters only in extraordinary cases where there is a clear and positive showing of manifest error and *783prejudice. Such a showing has not been made in this case.
