The Jecond modification of this firft pofuion, which may be 

 termed the nafal modification, is formed by opening the com- 

 munication or exit by the nofe, and fvifFering the found or 

 breath to pafs that way. In this cafe the letter m is founded. 



The fecond pofition is formed by the appUcation of the 

 under lip to the fore teeth of the upper jaw, which does not 

 form an abfolute interruption to the breath, but fuffers it to 

 pafs in an audible manner, by means of the reftraint with 

 which it is made to pafs. In this manner are produced the 



letters / and "v. 



The third pofition is formed by a fimilar application of the 

 tongue to the fore teeth, and a fimilar expreflion of the breath ; 

 thus producing the two confonants 6 and th. 



The fourth pofition is formed by the application of the point 

 or fore part of the tongue, to the root of the fame teeth, or fore 

 part of the palate. This forms a pofition that may be variouUy 

 modified, by means of the great volubility of this member 

 which is thus applied. 



In the firji of thefe modifications, the tongue is applied 

 clofely to the palate, fo as to form an abfolute interruption of 

 the breath, in a .fimilar manner to that of the firft pofition. It 

 may be therefore termed the mute modification of this pofition. 

 In this mute modification are formed the confonants t and d. 



In the fecond modification, the tongue is not kept clofe fixed 

 to the palate, but fuffers the breath to be expreffed in an audi- 

 ble manner, fimilar to thofe of the fecond and third pofirions. 

 This, then, may be termed the fibilating modification, by which 

 are expreffed the / and z. 



In the third modification, the paffage of the breath between 

 the point of the tongue and the palate is opened, and that by 

 turns, in a quick or tremulous vibration. It may therefore be 

 termed the vibratory modification, by which the letter r is 

 formed.
