During the progress of the trial the plaintiff of

fered to testify: “It was very dirty, and had the appearance of having been walked over, under foot.” Counsel for the defendant objected to this testimony as calling for an opinion of the witness. The judge ruled: “She can describe its looks, but not give an opinion about it. I will exclude her opinion. Let her describe what it was. She can give a description of what it was.” Thereafter the witness, as to this phase, testified: “It was more than a mashed leaf. It was mashed and it was very dirty. You could not tell whether it was green or what color it was.” As we view the case, we can with propriety concede but need not decide whether the ruling was error. Such would make no material difference in the law which would apply under the facts of this case. Let us then consider the excluded testimony as a part of the evidence. There is no evidence to charge the defendant with actual knowledge of the presence of the vegetable leaf upon the floor. Therefore we must look to see whether the evidence was sufficient to charge the defendant with constructive knowledge. There is no question but what constructive knowledge may be based on inferences drawn from the evidence, but the question in this case is whether the inferences which the law requires to charge the defendant with actionable negligence may be legally established by the evidence in this case. The measure to be' applied is that of circumstantial evidence. The rule is as follows: in civil cases dependent solely on circumstantial evidence, before a verdict is .authorized for the plaintiff the testimony must be such as to reasonably establish the theory relied on and to preponderate to that theory rather than to any other reasonable hypothesis. In this case the inference must be based solely on the location and condition of the leaf itself, and on its appearance of having been walked over, under foot. This court dealt with a very similar situation in
