PHILIP and PHYLIS MORRISON
The mechanisms of speech and voice are taken apart for readers in the upper grades [in Song, Speech, and Ventriloquism], with sensible model experiments and the tricky tests you can make with the black box of your own speech. Then the whole sense of understanding is put to real use, by building up a rationale from which anyone who will try hard, and practice, can become a genuine ventriloquist. There are even a few lines of properly old jokes. Original and intriguing, and possibly a low-key means of improving one's speech. (p. 151)

[Dreams is a] refined distillation of modern theories proceeding from simple to complex in a meaningful idiom. [This] demands from any reader the ability to make logical progressions from once-presented information, which restricts the potential audience. (p. 277)

Dreams, a topic important to all of us, is treated somewhat superficially [in "Dreams"]. This account explains their historical, psychological and social significance and gives brief mention to the symbolism used in their interpretation. It is in this last area that the book misses (probably on purpose) the major factor, sex. Because sex—at least to Freudians—is the dominant theme in dream symbolism, the subject (symbolism) might better have been ignored than covered inadequately in deference to the young age group.
