In the April 1999 issue (Volume 86, Number 2), there is a typographical error in the book review written by Paul Roazen. On p. 314, the sentence that begins in the sixth line of the first full paragraph should read, “Biological therapists are now apt to be as interested in family history and heredity as would have been the case among clinicians at the turn of the twentieth century….” (corrected word underlined).
