Mr. Justice Deyer delivered the opinion of the court.
3. Assault and battery, § 22*—when instruction on amount of damages for assault erroneous. An instruction, in an action for damages for an assault, authorizing the jury to assess plaintiff’s damages, if any, “at such sum as they believe from the evidence she is reasonably entitled to,” was erroneous, as the right of recovery should have been limited to the damages charged in the declaration. 4. Instructions, § 88*—when instruction on determination of preponderance of evidence erroneous. An instruction for the plaintiff advising the jury that the preponderance of evidence in a case “is not alone determined by the number of witnesses testifying to a particular fact, or state of facts,” and then enumerating the matters proper to he considered by the jury, omitting the number of witnesses testifying for and against, is erroneous. 5. Master and servant, § 867*—when ratification of wrongful conduct of servant in committing assault not shown. Evidence held insufficient to show that defendant railroad company ratified and acquiesced in the alleged wrongful conduct of its servant in committing an assault upon a person on its property. 6. Master and servant, § 867*—what insufficient to show acquiescence in wrongful act of servant committing assault. The fact that an employee of a railroad company who commits an assault upon a person on the railroad property continues in the employ of the railroad company is not sufficient to show knowledge of or acquiescence in the wrongful acts of the servant. 7. Master and servant, § 849*—what is effect of retention of employee on liability of master for assault by him. A railroad company is not liable for the acts of a servant committing an assault upon a person on the railroad property where it in no way participates in the acts, although it retains the employee after the assault. 8. Master and servant, § 836*—when doctrine of respondeat superior does not apply. The doctrine of respondeat superior does not apply where liability depends solely upon the contract of employment, so as to inflict exemplary damages upon the master for injuries resulting from conduct of a servant which he neither authorized, ratified nor participated in. 9. Master and servant, § 847*—when act of servant not act of master. The act of a servant is not the act of the master unless the aej complained of is directed or adopted by the master.
