Order affirmed, with costs to the Workmen's Compensation Board, on the opinion at the Appellate Division.
Concur: Chief Judge FULD and Judges BURKE, BREITEL, GABRIELLI, JONES and WACHTLER. Judge JASEN dissents and votes to reverse in the following memorandum: I would reverse the order of the Appellate Division and dismiss the claim on the ground that the record does not support a finding of "suddenness of causation" or "suddenness of result", an essential element of a compensable industrial accident. (See Matter of Greensmith v. Franklin Nat. Bank, 21 A.D.2d 576, affd. 16 N.Y.2d 973.)
