The Difficulty which is fuggefted about the Chyle's 
not getting Coon enough into th e. Blood, by the Way 
of the LaUeals , to produce this Effect in fuch as deep

confider, that this very rarely happens, at lead never 
attends temperate People, in perfect Health, and in a 
temperate Climate ^ but fuch as are grofs Feeders, 
Drunkards, Corpulent, Short-neck’d, by Conftitution 
or Make liable to Apoplexy or Palfy, or have for*

In grofs Feeders, Drunkards, and fuch as are Cor*

quite empty ; in fuch the Food of the prefent Meal, 
by exciting the periftaltic Motion, will, in a few 
Minutes, prefs forward the Chyle of the preceeding 
Meal into the Blood. In full Veffels or T uhes the Re-

In Short-neck’d People the Paffage between the 
Heart and the Brain being proportionally ffiort, the 
Force or Momentum of the Circulation in the Brain, 
is by fo much the greater; but a ftrong and fwift 
Circulation is an Enemy to all Secretions, as is evi-

the Secretions being bvlateral Branches going off ator
