This mistake can be seen in the second edition (1978) as republished by Dover in 1995: ISBN 0-486-68735-X

Mistake

 * "Every point is a component since every set containing more than one point is separated, ..."

Separated is the wrong word to use here, as that refers to the relationship between two subsets of a space.

The correct word is disconnected.
