Description
This longitudinal wave demonstration device came from Clemson College in South Carolina. The inscription on a brass plate reads “E. S. RITCHIE & SONS / BOSTON.” That firm termed it “Snell’s Illustration of Sound Waves, or Waves of Condensation and Rarefaction.” Ebenezer Strong Snell (1801-1876) was a professor of mathematics and natural philosophy at Amherst College who designed and modified several sorts of demonstration apparatus.
