Also, there was sufficient evidence, even though in dispute, to justify the jury's finding that the Hospital committed a breach thereof, entitling Mrs. Terrio to contract damages. Dube v. Simard, 124 Me. 369, 129 A. 488 (1925); Winship v. Portland League Base Ball and Athletic Ass'n, 78 Me. 571, 7 A. 706 (1887); Miller v. Goddard, 34 Me. 102 (1852). The Hospital asserts that prejudicial error resulted from the refusal of the presiding justice to grant eight requested jury instructions, and further objects to the charge as given. Specific requests for instructions must be seasonably presented to the court at the close of all the evidence and prior to the judge's charge to the jury in order to preserve for appellate review the issue of whether the requested instructions should have been given. Rule 51(b), M.R.Civ.P.; Simmons v. State, 234 A.2d 330, 331-32 (Me. 1967).
