On Certain Classes of Bounded Linear Operators, by Chia-Shiang Lin.Canad.Math.Bull.(4) 13 (1970), 469-473.On page 470, the last line in COROLLARY 1 should read "one element, B(X)".On page 472, COROLLARY 2 is incorrect and is replaced by the following: " On the other hand, if{T n } is a sequence in B(X) and T e B(X) with T e T convergence in norm, it may happen that T n $ ®(C\{d}) for «=1,2,..., even ifTT n =T n T. For example, let T n =I/n, then T n e ®({0})for n=l, 2,..., and r n ^r=oe
