concurring specially. It is my opinion that the request to review the case of Swicord v. Crawford, 148 Ga. 719, should be granted and the decision overruled; but since it is not possible to obtain that unanimous consent required by law in order to overrule that case, I concur in the opinion delivered by Mr. Justice Hines in this case in behalf of the court, in which the law is so clearly and aptly set forth, as well as in the judgment of affirmance.
