No person shall commence any suit against the Board or against any officer or servant of the Board or any person acting under the orders of the Board, for anything done or purporting to have been done in pursuance of this Act, without giving to the Board, officer or servant or person, as the case may be, two months' previous notice in writing of the intended suit and of the cause thereof, nor after six months from the date of the act complained of. And in the case of any such suit for damages, if tender of sufficient amends shall have been made before the action was brought, the plaintiff shall not recover more than the amounts so tendered and shall pay all costs incurred by the defendant after such tender.
