The complaint concerning the instructions is tihat the court did not give an instruction ' defining “probable cause”. There are two answers to this complaint. First, the motion and grounds for a new trial did not mention the instructions. True, 'it states, “there was an error of law occurring at the trial”, but this ground is "not 'sufficiently specific' "under the Civil Code of Practice, § 340(8) to question the *50correctness of the instructions. Engleman v. Caldwell & Jones, 243 Ky. 23, 47 S.W.2d 971; Chicago, B. & Q. R. Co. v. Blakemore, 250 Ky. 604, 63 S.W.2d 770. It is the familiar rule in this jurisdiction that where no objection is made to tihe instructions in the motion for a new trial, they cannot be questioned in this court on appeal. Oliver v. Muncy, 262 Ky. 164, 89 S.W.2d 617. Second, an appellant will not be heard to complain of the court’s omission to give an instruction when he failed to make á request for it in writing. Helge v. Babey, 228 Ky. 197, 14 S.W.2d 757. It is only fair to state here that counsel who represented Oakes on this appeal did not represent him in the trial court. The judgment is affirmed.
