The board may employ a carrier or carriers for conveyance of bodies, which must be well enclosed in a suitable case and carefully deposited, free from public observation. Every carrier shall obtain a receipt by name or, if the person be unknown, by a description for each body delivered by the carrier and deposit the receipt with the board or its authorized agent. After the bodies have been sufficiently used for the purposes of instruction, the bodies must be decently and respectfully disposed of by the university, college, physicians, or surgeons, as the case may be, receiving them.
