3. In a suit by an employee against a railway company for а personal injury. caused by thе running of a locomotive and the concurrent negligenсe of a eoemplоyee, it is error for the cоurt to give in charge to the jury thе provisions of section 2780 of Civil Code (1910), to the effect that when the injury is shown, a presumption of negligence arises аgainst the company; and such an error is not cured by subsequently giving, in effect, the correct rule, where the erroneоus instruction is not again referred to and withdrawn, or specifically modified. Wrightsville & Tennille Railroad Co. v. Tompkins, 9 Ga. App. 154 (
4. The further assignments of error are without substantial merit.
