ents oblige
them to an intense Application of Mind, which makes them very faintish:
to all these it agrees perfectly well, and becomes to them an altering
Diet.

On the contrary, I would not counsel the daily Use of it to such who are
very fat, or who are wont to drink a good deal of Wine, and live upon a
juicy Diet, or who sleep much, and use no Exercise at all: In a word,
who lead a delicate, sedentary, and indolent Life, such as a great many
People of Condition at _Paris_ are used to. Such Bodies as these, full
of Blood and Juice, have no need of additional Nourishment, and the
Diet will fit them better which is mentioned in Ecclesiast. _Plentiful
Feeding brings Diseases, and Excess hath killed Numbers; but the
temperate Man prolongs his Days[59]._

FOOTNOTES:

[1] The _Translator_ of this Treatise, who is a Physician, thinks it
proper to observe, that the Opinions about Digestion, are deficiently
related by our Author; for they are chiefly four, _Trituration_,
_Fermentation_, _Heat_, and by a _Menstruum_, which are so far from
being incompatible, that three of them necessarily concur to promote
Digestion; to wit, _Heat_, and a _Menstruum_ or _Liquor_, and
_Trituration_, or the Motion or rubbing of the Coats of the Stomach: For
it is plain, if the two former are absent, there can be no Digestion,
and without doubt the last does assist, but which is the principal, I
shall not take upon me to determine.

[2] Our Author seems here either to mistake _Ferment_ for _Menstruum_,
or to make them synonymous Terms: With this Allowance, his Reasoning is
undoubtedly just; but as for a Ferment, in the usual Sense of that Word,
it may justly be questioned whether there be any such in a Human Body.

[3] Our Author seems to make Phlegm and Spirit synonymous Terms in
Chymistry.
