Title: On Collectionwise Normality of Product Spaces. II
Abstract: In this paper the following results will be obtained. (1) Let $X$ be a closed image of a normal $M$-space and $Y$ a paracompact first countable $P$-space. If $X \times Y$ is normal, then $X \times Y$ is collectionwise normal. (2) Let $X$ be a collectionwise normal space and $Y$ a $\sigma$-locally compact paracompact space. If $X \times Y$ is normal, then $X \times Y$ is collectionwise normal.
