Thefe parts are reprefented by very exaft Figures, and the mat- 
ter for thefe Figures is furnilh't by the Ingenious and Diligent Dr. 
Edmund Kingy with great skill and dexterity ; as the Auehor hiin- 
Telf acknowledges in [he Dedication of this Book. 
From the Conformation of theL«/igxand the parts and Veffels 
' thereof, the Author infers, that the Ufe of the Lungs feems to Joim 
to be; That the Blood may be through the final ler Venels, like fo 
many little rivulets, difplayed and ex pofed in all its parts, and 
all thefe parts meet with the Nitrous particles of the Air, and be 
infpired with Vitality from the fame. 
Having explained tht Organs of Refpiration,he fearches into the 
£7<jAi/^of thateonftant viciffitude of the Syjlole dS\d Diajlole; and 
having afligned it to be the Ammal Spirits, rufhing out of the ten- 
dons mto the carneous fibres, to perform the Comradion of the 
Mufcles,and receding back out of thefe mothofe^ to perform their 
Relaxation : Having, I fay, done this, he fliews the different caufe 
of ihe Spontaneous aud themeerJVi/^r^/ fundi ion in Animals, deri- 
:ring the y2>mer from thofe Animal Spiiits that are difpens'd by 
the Cerebrum 5 the Utter kom thofe that are furnifli't by the Cere- 
hel!um\ proving withalj that Refpiration is, as *t were,a mix'd work 
parraking of both funftions, the fponc^neous and natural. 
After the examination of the ftrudlurc of the Lungs and the Parts 
thereof, ferving for Motion and the entertainment of Life ; he pro- 
ceeds to confider the various ways and accidents, by which that 
nux\\iQ]d afparxtus of organs may be vitiated , and confequently 
the funftions, depending therefrom, perverted ; efteeming,that this 
Pneumonique Engin, lodged in the breaft, whereby the Air being 
infpired, we maintain the life of the blood and its motion and heat, 
is exceedingly fubjefl to depravation ; as a Watch that is with 
great Art compofed of a fpring, ballancej, wheeles, firings, &c. is 
very liable to diforder. 
Herelie^liews, How the Ufes and Ends of Refpiration maybe 
fpoiled ; which is done chii fly two ways; Firft^ when the Blood 
does not duly circulate through the Heart and the Pneumonique 
VefTelsi which may fometimes be caus'd within the right ventri- 
cle of theheart,or the Pneumonique Arteries,fometimesalfo with- 
in the left ventricle, or the pulmonary veins: Secondly^ when the 
Air is either not duly infpired and expired in or out of the Wind- 
f)ipeand its branches:, Of each of which as there are various
