On November 12, 1943, we affirmed the judgment of the trial court. In view of the opinion of the Supreme Court in Simpson v. McDonald, Chief Justice, et al., Tex.Sup., 179 S.W.2d 239, our former judgment is hereby set aside, the judgment of the trial court is reversed, and judgment is here rendered in favor of appellants. Our former opinion reported in 175 S.W.2d 630, is withdrawn.
