The bodies received shall be distributed by the Board to and among medical colleges and schools of the State and such physicians and surgeons as the Board may designate. The colleges and schools shall first be supplied with bodies needed for lectures and demonstration. The remaining bodies shall be distributed equitably among the physicians and surgeons aforesaid; provided, that in such equitable distribution the physicians and surgeons as aforesaid of the city where the death of the person took place shall have prior right to receive the body. The Board, instead of by themselves or through their agents receiving and delivering such bodies, may, from time to time, either directly or by their officers or agents, designate physicians and surgeons to receive them and the number each shall receive. For the purpose of the distribution contemplated by this section, the body shall be held, subject to the order of the Board or their authorized agent, in the city where death occurs not less than twenty-four hours.
