Samuel Blatchford, New York Company v. Estill — Opinion of the Court
“ The court instructs the jury that the burden is not upon the defendants to account for the abortions amongst cows and heifers of plaintiffs, if there were such abortions, but upon the plaintiffs to prove and establish by a preponderance of the evidence that such abortions were caused by the collision alleged in the petition, and if, upon all the evidence, the jury are not convinced that such abortions were caused by the injury, they should not allow damages for such abortions, although they may not be able to determine from the evidence what the real cause of such abortions was. ”
