feveral Diftempers that are called Nervous^ may atife, 
and are more likely to be cured by correding and eva-

from the common Clafs of Nervines,

the Co-operation of the Bile : And therefore it is 
probable, that the Difference of Conftitutions, at equal 
Ages, with refpeft to Purgatives, depends more upon 
the Quantity and Quality of the Bile, than on the 
Bulk or Weight of the Quantity of the Blood, or 
other circulating Humours.

due Quantity and proper Quality of this Juice, with- 
out which the Blood and circulating Humours coma 
not be recruited from the Prima Fia : And there-

a Marafmtis, or Wafte of the Body, where it is little 
fufpefled : Which may ferve to point out the Methoa

ledge of the immediate Caufe of natural Reft ot Sleep 
in a healthy State ; to wit, a certain auantity or Pro- 
portion of frefti Chyle in the Blood ; the Want of 
which, from whatever Caufe, will occalion Watchtul- 
nefs or fome Degree of it. And this may ferve to 
Doin\ out the immediate Effed and Confequences of 
ODiats, whence may be gathered how far and in 
what Cafes they may be effeaual and ufeful ^ and in 
what Circumftances they may be iiieffeaual, ufelefs 
or hurtful. Which may deferVe a farther Uluftration.
