is relaxed by recent
fatigue and digestion. These qualities being the most proper to produce
fresh animal spirits, are the most fit to be taken when a new accession
of them is necessary. It has been observed those are the most robust
whose serum resembles most the white of an egg. It has therefore been
most rationally concluded, that the origin of the animal spirits is
from aliments capable of being changed into a similar substance, but so
attenuated by incalation as to concrete by fire. For this reason the
greatest support of the spirits is afforded by light and nourishing
meats and drinks, which in taste and smell are even agreeable to
infants. All cordials and aromatics are consequently the most proper
for such purposes, and at such times, when heavier foods would impress,
instead of recruiting, the exhausted solids and fluids. It is therefore
Boerhaave recommends such aromatics, for the reviving and recruiting
the animal spirits, as have the most pleasing taste and smell.
Agreeably to this opinion, Dr. Solander employed his researches to form
an afternoon beverage of such herbs as should possess all the above
cardiac and balsamic qualities. The use of the sanative tea between
dinner and supper operates as the most reviving and wholesome aliment
that can, at such a time, be possibly taken. An enquiry having been
made into the nature, preparation, and manner of using the sanative
tea, there only remains to conclude this Second Part of the Essay with
the consideration of its

EFFECTS.

From the view that has been taken of the nature, preparation, and
manner of using, the salutary effects are most clearly and easily to be
ascertained. As the basis of this tea is the combined principle of the
most balsamic oils, nutritious salts, and animating sulphurs, which the
vegetable world produces, their effects must be proportionably
salutary. And as their combination is such as to correct the pernicious
qualities of each other, their conjoint effect must be the most
wholesome that can possibly be administered for the health of human
nature. As every simple, however specific in certain cases, possesses
qualities that are pernicious in other respects, it has been the first
principle of physical enquiry not only to find the basis of a medicine,
but to form compounds or ingredients that corrected the injurious
tendency of each other. With this scientific principle Dr. Solander
having composed his sanative tea, has rendered it th
