(3)The evidence of each witness after it has been recorded as provided in the rule when taken down, shall be read over to him, and shall be signed by him, or if he cannot write his name shall be attested by his mark and witnessed as a token of the correctness of the evidence recorded. After all the evidence against the accused has been recorded, the accused will be asked: "Do you wish to make any statement? You are not obliged to say anything unless you wish to do so, but whatever you say will be taken down in writing and may be given in evidence." Any statement thereupon made by the accused shall be taken down and read to him, but he will not be cross-examined upon it. The accused may then call his witnesses, including, if he so desires, any witnesses as to character.
