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