As a contination of the previous paper [1], in which an appoximate solution of one-dimensional freezing equation for fish fillets has been given for the case of a rather small value of Brot's number by applying the well known KARMAN-POHLHAUSEN'S method in the theory of boundary layer equation, the author, in this paper, attempts to solve the same problem for the case oi iniinitely large BIOT's number with the aid of YAMDA'S method [4], which gives as the zeroth approximation the result obtained by KARMAN-POHLHAUSEN'S method.
