91.—Unless a contrary intention appears from the will, any estate comprised or intended to be comprised in any devise or bequest contained in the will which fails or is void by reason of the fact that the devisee or legatee did not survive the testator, or by reason of the devise or bequest being contrary to law or otherwise incapable of taking effect, shall be included in any residuary devise or bequest, as the case may be, contained in the will.
