ABSTRACT. 
The construction of the instrument is such that a finely-pointed glass pen, placed at 
the junction of two cranks proceeding from the top of two pendulums vibrating at right- 
angles to one another, traces curves on a sheet of paper. Attention was drawn te the 
endless variety of curves produced by varying the length of one of the pendulums ; and it 
was pointed out that the curves were then only symmetrical when the ratio of the times 
of vibration corresponded to a definite interval in music, as a third, fifth, octave, etc. In 
other cases asymmetrical figures were produced.
