From what has been seen it seems there are three classes of cases in which convictions for larceny at common law may be had where apparent possession is in the accused; first, where the accused has the mere custody of property as contradistinguished from possession, as in the case of a servant and the like; second, where he obtains the custody and apparent possession by means of fraud or with a present purpose to steal the property; and third, where one has acquired possession by a valid contract of bailment, which is subsequently terminated by some tortious act of the bailee or otherwise, whereby possession reverts to the owner, leaving the custody merely in the former, and the bailee, while being thus a mere custodian, feloniously converts the property to his own use.27
