k, the hurry of play, the pursuit of health, or the
training of the mind we miss the very thing which can give meaning and
value to all these things. The severely matter-of-fact people don't go
near the curtained doors, and if they did, would discover only a lot
of cold, lifeless statues. Whoever heard of statues dancing? Whoever
heard of music without instruments? And yet this very sense of a
lyrical movement imperfectly seen, and of a temporarily frozen music,
is not only the very secret of all art: it is a slender guiding clue
to the centre of everything....

And in the house of every man, and of every woman, are the curtained
doorways.

HOW MUCH SHOULD WE EAT?

_This discussion arose out of the article with above title, by "M.D.,"
which was published in our July number._--[EDS.]

I lift my hat to M.D. and trust that, as I don't know him, the
somewhat jarring difference that I have with his views will not be put
down to personal feeling. A.A. Voysey has put my first objection quite
well from the layman's point of view. He says "there is no agreement
between those who have been taught physiology." This is true.
Playfair's full diet is different from Voit's. Voit's is different
from Atwater's. Atwater's is different from Chittenden's.

The custom of reducing the diets to calories, inasmuch as it
introduces a false theory, has had a disastrous effect on progress,
and has been a great hindrance to the attainment of knowledge. If the
coal in the fireplace _were_ the cause of the heat of the fire (but is
it?), there is no analogy between the elevation of the heat by
hundreds and even thousands of degrees when the fire is lighted, and
the elevation of half-a-degree or a degree which occurs when food is
taken into the body, especially when we remember that a similar
elevation of temperature occurs when work is performed by means of the
body without eating or drinking at all.

It is quite evident to every clear seer, or it ought to be, that the
force of animal life or zoo-dynamic is the cause of the heat of the
body, just as the electric force is the cause of the liberation of
heat through the battery, and the chemic force is the cause of the
heat of the fire, and that zoo-dynamic and electro-dynamic and
chemico-dynamic are forms or species or varieties of the one
omnipotent and eternal energy by which all things in this universe
consist. The aggregate of all the particular forces make
