Whenever any estate, real or personal, shall be devised or bequeathed to a child or other descendant or relative of the testator, and such legatee or devisee shall die during the lifetime of the testator, leaving a child or other descendant who shall survive such testator, such devise or legacy shall not lapse, but the property so devised or bequeathed shall vest in the surviving child or other descendant of the legatee or devisee, as if such legatee or devisee had survived the testator and had died intestate.
