Experiences with Sound, Volume VI, Science Teaching Today

Experiences with Sound was written and, perhaps, illustrated, by Guy V. Bruce. The book was published by The National Science Teachers Association in 1951, is a stated Fourth Edition, and a Volume VI in their Science Teaching Today series. It's not an ex-library copy, and is in very good condition though it does have some underlining and annotating in the margins by a former owner. The book is 7 1/2" by 10 1/8" and has 44 pages with a Table of Contents and black-and-white illustrations throughout the book. Thank you.
