Railroad Company v. Gladmon

[The care of the defendant is to be tested by the exercise of adult judgment in treating undeveloped judgment in childhood. The defendant, in his duty under the law, is to be held to the exercise of adult judgment and caution when brought to bear upon the security of childhood and undeveloped judgment, and as a convertible proposition the child is to be held to the measure of childhood judgment; and I will give you some of the reasons for this determination:] This corporation, under the operation of its charter, the authority of the law of its existence, is permitted to occupy the common thoroughfares of this city. It is created to move in those thoroughfares with the machinery that it has adopted as a carrier.
