otherwise provided by law, the director or other person in charge of

which shall provide for their payment in the same manner as other
charges against the county.

2. The board of supervisors of a county not having a purchasing agent
may make an appropriation for the maintenance of such laboratory and

wages which are approved by the director of the laboratory within the
amount of such appropriation, subject to such regulations as to the
payment and audit thereof as the board of supervisors may deem proper.
