THis Author is ©f opinion, that all thofe Philofophers, who 
have hitherto inquired into the iV^^/zr^ and Z//^ of Refpra- 
fmj have only caught the fliadow of it, nothing of the fubftance. 
And of this he gives this for the chief reafon^ becaufe they have 
been too negligent in confidering the firftmanifeft motion of the 
Breaft and Lungs in a Fdtus $ which particular being underftood, 
he thinks it very eafie to judge of the Refpiration of born Animals. 
Hefcruples not to reprehend the immortal Dodor Harvej ^ for 
having excluded from the office of the Lungs the Vfe of Refrigera- 
tion which he pretends to have aflerted himfelf by moil evi- 
dent Experiments, and uncontrolable Reafons. 
To reprefentdiftindlyjwhat he undertakes to make out in this 
7r4^5 we may take notice of thefe particulars : 
1 . He takes pains to refute the Dodrine of AttraSiiony and to 
fubftitute in its place the Do(51;rine of Pulfton or Intrufion of Air in- 
to the Lungs. 
2. He endeavours to affert, that the Lungs do not fall dopi^n^ 
but are by the Breft contra^ed, 
3. He affirms, to have clearly fhew'd, what is the proper fun- 
dion and work of the Diafhragnie^ and Qih^xMufcles fervingfor 
Refpiration. 
4. He pretends, to have experimentally evinced the Genuine 
life oi Refpiration^ and the Benefit thence refuking to the Ani- 
mal Life,
