expiration, or attended with the guttural found. This then 

 forms two cafes of articulation, differing from each other, 

 and alfo from the other two cafes of mute articulation ; feeing 

 that in the prefent cafe, whether the confonant be formed with 

 a guttural found, or only an audible afpiration, it is a conti- 

 nued thing, and is not neceffarily terminated, as in the mutes, 

 by the clofe pofition of the organ. Now, as in the cafe of 

 mutes, we have the diftinction of perfect and imperfect, with 

 regard to that fpecies of letter, fo, in the cafe of confonants, 

 we have a fpecies which is perfect, and one which is imperfect. 

 The imperfect fpecies of confonant-articulators, is formed 

 in the four fibilating portions and modifications jufl now men- 

 tioned, viz. the f in the fecond pofition, the 6 in the third po- 

 fition, the f in the fibilating modification of the fourth, and 

 the jh in that of the fifth pofition. 



To perfect thofe four confonants, we have but to add the 

 guttural found to the continued expiration ', and we then pro- 

 duce of the / the v, of the the tb, of the / the 2, and of the 

 Jh the j. 



We have now only remaining the nafal modification of the 

 firft pofition, which gives the confonant tn ; the vibratory mo- 

 dification of the fourth and fifth pofitions, which give two fpe- 

 cies of the letter r ; the liquid modifications, which give two 

 fpecies of the letter l\ and the nafal modifications of thofe two 

 laft pofitions, which give two fpecies of the letter //. In none 

 of all thefe, is there formed a diftinct articulator, by means of 

 the fimple afpiration ; confequently all thefe are perfect confo- 

 nants. 



The alphabet is thus completed, in comprehending every 

 poflible vowel and articulator which are proper for diftinct 

 fpeech, except the audible afpiration of the letter h ; and this 

 is a general articulator, which is formed in many different pofi- 

 tions of the vocal organ.
