t!ie fanguineous receptacle he iikewife confiders two kinds of 
contents , one whereof is the Chyle, which by various cribrations and 
circuUtions,at laft conaes to conlUtute the whole fiiafs of bloud ^ the 
other, the Ljmfha\ ynhxch, having been fecret^d from it, is afterwards 
refunded to ic. And, to esplaiH hoiv tbrc motion, both of the whole 
mafs of bioud,and of the humors, to be fecrcted from i**, depends upon 
the carneous fibres, he fuppofes a channel without beginning or end, 
- from ore part of which he fuppofes other channels to branch, and to 
return again circularly into it • all the branches in the mean while 
obfervinga proportion to that part of it, from w^hence he begins the 
divifion (defcribing it by two figures,) which he applies tothe feverai 
parts, and the motion of the liquors through them. After which he un- 
dertakes to confute the opinion of fome that think the Humours, by 
their cfFervefcence, have a great hand in the contra<flion and dilatati- 
on of the heart, afcribing the bufinefs wholly to the motive fibres of 
that raufcle. Then he touches upon the opinion of fome, that the Ar- 
teries have a periftaltick contradion, but forbears to determine it : 
Oniy , fecras to like Dr Thrnlien'i CQnjedture,about the Sjjfahick moti- 
on of the circumjacent parts, for returning the bloud along the veins 
to the heart-, but adds, that it might with more probability be faid, 
that the return of it by the veins , is not only from the propulfion of 
that which comes out of the arteries into them, but from the proximity 
of thofe two kinds of veffels, and the mediation of their coats ^ the di- 
latation of the arteries, in regard they all along joyn laterally to the 
veins, helping tlie protrufion of the bloud from valve to valve toward 
the hearf.And though they are feparatcd in the lungs by the bronchia^ 
yet the air upon infpiration ^according to Thrnfions ingenious fuppo- 
iition) does, he imagines,the fame thing.Laftly^to confirm his afTcrtion 
about motive fibres being the caufe of this motion of the Hu(pours,he 
cites ^^//?<^/?i;«*sobf€rvation, about the rf/^/i« of the fplecn, where, 
becaufc there is not a fufiricicnt compreffion , ttie afFufed blood does, 
after a fort, ftagnate. 
From hence he proceeds to confider the Excretory veffelsof this 
Receptacle. Among which, in the firft place he reckons the Nerves, but 
leaves their farther confideration as too obfcure ; Next the Lyropha- 
ticks, which f after others) he will have to arifc from conglobated 
glandules. Of thefe veffels he affirms many to be in the Spleen, and 
(hews his way to make them appear to view ^ He feems alfo to own 
fome of them in the Liver, though Mdlplghim doubt of them s offers to 
fliew thofe of the Kidneys to any that delire it •, will not determine a- 
ny thing concerning thofe, which i$*n^4»;w^r^4»? fuppofes to proceed 
from the glandule? of the inteflincs, if they are diftinft from the VAf4 
/a^ea, which he alledges he has once or twice found full of clear iym- 
p^4,when he has opfened the animal two hours after meat ibut declares 
that nab difcovered, f at ieaft affirms, that he has not met witb the 
fame obfervation made by any other, / and in feveral fubjeds con.
