The opinion
Per Curiam.
The orders denying the motions to compel discovery are subject to review on an appeal from the final judgment of the trial court. Mandamus is not a substitute for appeal. State, ex rel. Marshall, v. Keller (1968), 15 Ohio St. 2d 203, 205 .
The judgment of the Court of Appeals is, therefore, affirmed.
Judgment affirmed.
Celebrezze, C. J., Herbert, W. Brown, P. Brown, Sweeney, Locher and Holmes, JJ., concur.
