Mr. Tomlinsons Experimenis and [Aug 



O 



The figure of the bell represents that of Salisbury Cathe- 

 dral, the dimensions of which I find to be nearly as follows :— 



Feet, Inches, 



Diameter 



Circumference at bottom . 

 Circumference at top . . 

 Depth 



1. The fundamental tone, E flat. 



2. The third harmonic, G. 



3. The fifth, B flat. 



4. The octave, E flat. 



5. The acute harmonic, E flat. 



6. The grave harmonic, E flat. 



The average thickness of the vertical parts of the bell 

 seems to be about three inches and a half, or four inches.
