A tape recording of part of the proceeding having been lost so that no transcript can be made as required by V.R.A.P. 10(b), the cause is reversed and remanded. Cf. Wemyss v. Viens, 125 Vt. 81, 211 A.2d 238 (1965) (notes of trial stenographer lost so lack of transcript prevents appellate review); State v. Harvey, 135 Vt. 549, 550, 382 A.2d 210 (1977) (record below “so fraught with error that a just review” is impossible).
