Elementary Lessons On Sound – Circa 1879

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.
