is not
unreasonable or unnatural, and is consistent with itself, and where
the witnesses have not, in any manner, been impeached, then you
have no right under the law, to disregard the testimony of such
witnesses from mere whim, caprice, or without just cause. It is the
duty of the jury to consider the whole of the evidence, and to
render a verdict in accordance with the weight of all the evidence
