lightful music is produced. Mr. Puckeridge, an 

 Irish gentleman, about the middle of the century, 

 was the first who contrived to play regular tunes 

 on an instrument of this kind. After his death 

 Mr. Delaval, an ingenious member of the Royal So- 

 ciety in Great Britain, made a musical instrument 

 on the same principles, but with a better choice 

 and form of glasses. In this stage of the invention 

 Dr. Franklin undertook to investigate the sub- 

 ject, and considerably improved upon Mr. Dela- 

 val's plan, giving it the name which has been 

 mentioned *. Since Dr. Franklin, Dr. E. Cullen, 

 of Dublin, has formed an instrument of, the same 

 nature, but much more extensive and compli- 

 cated, which he thinks so different as to require 

 a new name. The erreat excellencies of the Har- 

 monica^ as an instrument of music, are, that '' its 

 tones are incomparably sweet, beyond those of any 

 other; that they may be swelled and softened at 

 pleasure, by stronger or weaker pressures of the 

 iinger ; that they may be continued to any length ; 

 and that the instrument being once well tuned, 

 never again wants tuning." 



The century under consideration has also pro- 

 duced a new species of musical instrument, called 

 i\\Q EKphon, invented in 1790, by Dr. Chladni, a 

 philosopher of Germany. Like the Harmonica, 

 it is performed with the hand, on gla-ssts ; but it 

 differs from that instrument in several respects. 

 Tlie music of the Harmonica is produced by rub- 

 bing the edges of glass vessels, in a circular direc- 

 tion ; whereas the music of the Euphon is effected
