POPULAR SCIENCE REVIEW. 
It will be observed that, tbe diagrams of the separate words, 
although they become modified when grouped together, are 
more or less discernible in the lines continuously spoken ; and 
the similarity of sound at the termination of the first three 
lines, which constitutes the rhyme of the verse, is represented 
in the similarity of form, or in the character of the form, of the 
terminations of the diagrams of these three lines. 
The subject might be pursued much further by showing the 
diagrams of the same words spoken by different individuals, the 
outlines produced by the words and sentences of other languages, 
the effect produced by change of accent, &c. 
My object, however, has not been to pursue the subject into 
minute detail, but to show that the articulation of the human 
voice is accompanied by definite pneumatic actions, and that 
those actions, many of which are insensible to ordinary observa- 
tion, are capable of being recorded . — A Paper read before the 
Royal Society , April 16, 1874.
