by thefenfe, but follows by a parity of reafon ; contrary to 

 what Des Canes p afferts, that fuch vibrations are found on- 

 ly in upper thirds and fifths. 

 208. From the fame Principles may be (hewn how a Man may 

 ftrike any two Notes with his mouth at the fame time. For ifa Man 

 open his mouth in two places at once, as AB to BC, Fig. 1 7. or as 

 1 to 2 both in length and bredth, and then force out the breath 

 ftrongly againft them (thus opened) fo that the found be all begot- 

 ten there (as in whittling) you will hear diftincY and perfect 

 oflaves,per Princ. 2. And fo fecondly,if a Man can open his lips as 

 BC toCD,Fig. 1 8. or as 2 to 3 in length & bredth,and do as before, 

 he will ftrike fifths, per Princip. 2. And after the fame manner for 

 the reft of the Notes, according to the divifion of the Monochord. 

 2.09. According to which Hypothecs one Hooper here of Oxford 

 could fo clofe his lips, as to fing an ottave at the fame time. And 

 I know two other perfons now living here, that can do it though 

 their lips feem not to be fet in that pofture, yet they Unit them fo 

 clofe that they can by no means pronounce any thing articulate. 

 "But he that excels them all, and indeed to a miracle, is one Mr, 

 Jojhuah "Dring, a young Gentleman of Hart-hall, who lings a Song 

 articulatly,orepatulo,2nd all in oSlaves fo very ftrongly ,& yet with- 

 out much ftraining,that he equals if not excels theloudeft Organ*

 the Epiglottis and Vvula be both concerned in it, one founding the 

 upper, and the other {he lower ollave ; or either of them apart, o- 

 pening unequally as 1 to 2 in Fig. 1 7. or which is moft likely of 

 the three, by an unequal application of the Vvula to the Epiglot- 

 tis. For his own part he can give but little account of it himfelf 

 only that he performs it in the lower part of his throat, and that 

 it came cafually on him atfirft, upon draining his -voice ; yetmuft 

 it not be reckoned a meer cafualty neither,for he rings thefe oftaveS, 

 or otherwife (and both very ftrongly) according to pleafure. 

 And this is all I know of new, concerning the Mathematicks, ex- 

 cept there be any thing of Chorcgraphy in the Map of Oxford-fiire 

 prefixt to this Ejpty, that may be thought worthy the name of a 

 new Contrivance. 



211, In Natural Pbilofophy* Medicine and Anatomy, there have 

 alfo been many new Inventions and Improvements, made of later 

 years in this Vniverfity, which as they promifcuoujly fell out in order
