Thefe ar€ the Vowelsj each of which are long and fhort. 
Short as in the words, God, Man, Sin. 
Long as in Ball, Demand, Seen^ &c, 
Qf Diphthongs 
A Diphthong in the ordinary ufe of the Word fignifieth a 
Compound of two Vowels, but thofe in ordmary fo 
named, are moft of them nothing, but only fingle Vowels, 
as ea, oo, ou^ eOy ai^ in the Words teal^ tool^ tould^ people, mam, 
&c. That thefe are but fingle Sounds will appear, if we 
confider the Sounds of the Vowels fingly, that make thofe 
fuppofed Compofitions, and then whether thofe Sounds in 
Compofition will make out the true Sound required ; fb as 
both of them may be clearly difcern^d m thefe pretended 
Compounds. For inftance; in in Te'^/. 
Confider the Sound of e in the Word fenty or in the Word 
fce^e ; and a in the Word hall, or in the Word and, or in the 
Word tale, and then whether in either of the two Sounds 
going before, and a in either of the three Sounds following 
joyned together, will make out the true Sound of ea in the 
Word teal, if not, then is it a fingle Sound; thus, if you 
proceed to examine all the other, you will I doubt not had 
the fame event, and I believe the true Diphthongs and Tri« 
fhthdngs of the Greeks were no other but a true expreflion of 
the fiiigle Vowels they joyned together, but in fb fhort a 
time, as both or all three were exprefsM in the time that 
ordinarily one fingle Foml was exprefs'd.
