opinion: Per Curiam.
  The petition for writ of certiorari is granted. The judgment of the Supreme Court of Missouri is reversed and the case is remanded for proceedings in conformity with this opinion. We hold that the proofs justified with reason the jury’s conclusion that employer negligence played a part in producing the petitioner’s injury. Rogers v. Missouri Pacific R. Co., 352 U. S. 500; Webb v. Illinois Central R. Co., 352 U. S. 512; Shaw v. Atlantic Coast Line R. Co., 353 U. S. 920; Futrelle v. Atlantic Coast Line R. Co., 353 U. S. 920; Deen v. Gulf, C. & S. F. R. Co., 353 U. S. 925; Thomson v. Texas & Pacific R. Co., 353 U. S. 926; Arnold v. Panhandle & S. F. R. Co., 353 U. S. 360; Ringhiser v. Chesapeake & O. R. Co., 354 U. S. 901; McBride v. Toledo Terminal R. Co., 354 U. S. 517; Gibson v. Thompson, 355 U. S. 18; Honeycutt v. Wabash R. Co., 355 U. S. 424; Ferguson v. St. Louis-San Francisco R. Co., 356 U. S. 41.
  Mr. Justice Harlan concurs in the result for the reasons given in his memorandum in Gibson v. Thompson, 355 U. S. 18, 19. See also his dissenting opinion in Sinkler v. Missouri Pacific R. Co., 356 U. S. 326, 332.
  For the reasons set forth in his opinion in Rogers v. Missouri Pacific R. Co., 352 U. S. 500, 524, Mr. Justice Frankfurter is of the view that the writ of certiorari was improvidently granted.
