Whenever this readmifCon of Choler and Pituita hap- 
pens by the La^ea (which it does in moft Difeafes) we are^ 
then fick 5 the Primary and radical Humours of the Body 
being contaminated with their own Excrements i which 
had been once expelled. 
So that the Antients are beft underftood in this fenfe, 
when they tell us, that ?ttmta caufes cold Difeafes , and 
eiioler, hptones : that is, the extraneous Pitrnta^ind Cho- 
ler readmitted i not that the habit of the Body did abound 
with them , or breed them now in greater quantities j 
but inftead of a total ejedion, the evil gueits iteai in a- 
gain, and Nature labours as it was in vain. 
That the Chyle it felf too, is often in fault , and is to be

fiuous Chyle or extraneous Choler and Ptmta readmitted, 
or with the red blood it felf. Hence alfo true Indications 
may be taken for the cure of Difeafes ; and the known 
vertues of fimple Medicaments , according as they have 
been delivered to us by the Antients, more certainly 
applyed 3 becaufe thefe notions come neareft their do- 
citrine, and confequently will more faciHtate a practice de- 
duced therefrom. This Dodtrine I have alfo illuitrated 
with fome few cafes in Phylic j fee the Treatife. 
A Theory of Health and Difeafes being briefly laid down, 
as they relate to the humours 5 we proceed to enumerate
