The Health Commissioner shall be a physician of good standing in his profession. It shall be his duty to administer to all charity cases that he may, in his discretion, deem deserving. He shall, in conjunction with the City Manager, have charge of the general health and sanitation of the City, and it shall be his duty to carefully investigate all complaints and make a careful detailed report to the Manager and Council, at least once every month. He shall be appointed in the way and manner provided by this Charter and shall receive such salary as Council may by ordinance prescribe. Nothing herein, however, shall be construed as in any way affecting the police officers of the City relative to their powers and duties in regard to City sanitation contained and set forth elsewhere in this Charter.
