increase of the apparent size, all of which are to intimidate the
enemy, like an Indian's painting of his face blue and green. It
also--but what else does it not do?

The story of adrenalin would have delighted the heart of Samuel
Butler. His "Note Books," opulent as they are, would have been the
richer in pages and pages with his comments on it. Contending as he
did with the pompous, dogmatic mechanism worship of the new scientific
clique of his time on the one hand, and the superstitions of the old
theological caste on the other, he had to fight the hardest kind of
guerrilla warfare in defense of the Purpose of Life. Adrenalin, that
weapon of a gland tracing its ancestry back to the begetter of the
brain itself, for brain and adrenal gland both have evolved from the
small nerve ganglia of the invertebrates, would have backed up to the
hilt his argument, which he had to elaborate on the indirect grounds
of analogy and induction. Essential for defense, and for protection,--
an organ in which everything necessary for the stratagems of retreat,
or the offensives of attack, are supplied ad libitum, while everything
non-essential or detrimental to the matter of the moment is inhibited,
arrested and suppressed--no more perfect sample of the design with
which Life is drenched could be imagined by the most closeted of
passionate idealists.

FAILURE OF THE ADRENALS

As the gland of acute stress and strain, the adrenals in modern life
are called upon to function more heavily and frequently than in the
past. As a matter of fact, the life of the beast of jungle and field,
as well as of savage and barbarian, is just as full of emergencies and
shocks as that of the average city man or woman. In the case of the
latter, however, inhibitions, education, and the conditions of modern
living, improper food, sedentary indoor confinement, and universal
rack and noise, have undoubtedly made greater and greater demands upon
the adrenal glands. Chemical quantitative studies have shown that by
repeated stimulation, the adrenal glands may be exhausted of their
reserve supply of secretion, which returns only insufficiently if not
enough time is given for recuperation. There results a condition of
temporary or chronic adrenal insufficiency, supposedly an insufficient
functioning of the gland as a whole. In persons so afflicted there
appears a fatigability, a sensitiveness to cold, cold ha
