The difference also is seen to exist
in spite of an increased amount of bodily exercise."
As final deductions from these experiments, there result, first, "that,
when the diet is sufficient, the body _is_ more likely to gain weight
when tea is taken than when not"; second, "that, when the diet is
_insufficient_, tea _limits_ very much _the loss of weight_ thereby
entailed."
A set of experiments made by Dr. Lehmann are parallel with these. They
exhibit the effects of coffee on the excretion of phosphorus, chloride
of sodium, (common salt,) and nitrogen. If less full than Dr. Boecker's,
they appear to be equally accurate, and more complete in showing the
separate actions of the several constituents of coffee. It would be
tedious to the general reader to follow them in detail, and we shall
avail ourselves of the brief _resume_ of Dr. Chambers.
"First,--Coffee produces on the organism two chief effects, which it is
very difficult to connect together,--namely, the raising the activity
of the vascular and nervous systems, and protracting remarkably the
decomposition of the tissues. Second,--that it is the reciprocal
modifications of the specific actions of the empyreumatic oil and
cafeine contained in the bean which call forth the stimulant effects of
coffee, and therefore those peculiarities of it which possess
importance in our eyes,--such as the rousing into new life the soul
prostrated by exertion, and especially the giving it greater
elasticity, and attuning it to meditation, and producing a general
feeling of comfort.
