fo the opinions of Phyfitians concerning the Caufe of Hunger, 
anclfubjoyninghis own,illuftratedby Hiftories,fhcwing, that 
fochas havefafled for, a couple of day es, are not then fenfible 
of hunger, ancj find no other trouble but that of feeblenefs of 
Body. Here alfo he difcufles three Problems; i.Whac is the 
Caufe of Unnatural Appetite,call*d J?/w^Which caufe he plac- 
eth rather in the Brain than the Stomach, 2. Whether in a deprav- 
ed conftitution and concofiion of theftomach,theBilemay be 
made in the fame, fuch as in the Cholera, morbus is voided both 
upward and downward ? Which he denyeth againft l?<fg/W and 
others. 3. Whether ^//the Chyle flows out of the ftomach into 
the Guts ? Which he anfwers in the Affirmative, refuting thofe 
thataflert, part thereof to pafs by the vas breve and other 
neighbouring gajlric veins into the Spleen ; and affigning the 
manner ofthefudden refefiionof the body after eating and 
drinking. 
This done, he difcourfes of the Ufe of the Chyle, and in-

Treating of the ^Mefenter^, and the many and confiderable 
Glanduls thereof, he obferveth , that from the obftrudiion of 
thofe Glanduls, Fluxes and Atrophies are frequently occafio-

glanduls of the Mefentery the root of all ftrumofity. 
Examining the Papfcreas^ he reproveth thofe that would de-

ated humor of the PancreasiWh^re he alfo rejefts Dr. Whart9n's 
opinion concerning the life of this part, viz. that into it are 
voided the excrementitious juices of the Nerves. 
Searching into the ductus thoracicus ( the conveyer of the 
Chyle,) he declares, that that winding Circle of De Bills, into 
which he affirmed the faid du£tt4s to be propagated at the place 
of the divifionofthe Jugular veins, is notaprotraAioriof that 
ductus^ nor receives from it any chyle , nor carries any 5 but a
