the pores ; butthat did not latisfaftorily fuccced^ it coming 
oat in a confufed irroration of the external lurface ^ withoos 
any ebullition^ iinlefs at the larger ramification of the brem- 
<;hm. Then 1 tyed up this fecond lobe, and untyed a third^ 
powring in an ounce of the oyl of turpentine , at the fyphoa 
I gave a fmall blaftj and corked it up. Two hours after! 
took off ihe fmali membrane of that lobe, and upon a gentle 
blaft at the fyphon found an ebullition of infinite little 
bubles* 
Mard icth (having cootinued it to the chimney,) I cut 
all the lobes in pieces by different and varioifs irregular incifi* 
ons y whence I could eafily obferve the (everal ramifications 
of the aerial and fanguineous veffels, with their continuatfon 
to the circumferenceof the lobes, and a proportionable dimia 
nution as tfiey were at a further diftance from their origi* 
naL '-^ 
Shall I hence conclude the Scrufture of the Lungs to be a 
Complication of a multitude of the Ramifications of the bron- 
chise and fanguineous vcflfels ? And that the feeming veficles- 
were occafion'd only by the violence of the blaft^ and the 
drinefs of the extreme and fmalleft paflages of the Aerial vef- 
fe!s 5 whereupon thofe^neareft to the ir one bm{heingmoi&cr^y 
were, more thantheir ordinary proportionj extended, upon 
hindrance of a freeand ufual pafTage, to the Aip in the leffer 
veflTcIs or their extremities ? 
iThefc cafes I leave, with the manner of the Air's being 
eommixt with the blood in the Lungs ( which I think no hard 
matter plainly to difcover, J to the Firtmj? oi our Age, who 
have infinitely more advantages for the dikovery of Nature's 
works, and to whom I cannot imagine this fcrible to be any^ 
novelty. In which uncertainty I leave it to youc difcretjon toi 
do with it as you pleaf e« .
