Once again The Internet Archive provides a gem from the past. “Elementary Lessons On Sound” by W.H. Stone was published in 1879. The author demonstrates and explains the physics of sound using the technology of the time; metal rods, a bench vise, vibrating plates, tuning forks, etc.
I have to admit that I have looked at the pictures more than the text.
