e orthopaedic
ward, a physio-chemical clinic, where every evening the pupils, as
they leave the beneficent suspensory apparatus which counteracts
injury to their skeletons, may enter with a kind of ponogenic
prescription regulated by the teaching they have undergone, and
receive an injection which will deliver them from the poisonous
effects of fatigue!

This reads like an irony of the worst kind, perhaps; but this is not
the case. Where the orthopaedic institution is already an accomplished
fact, we may very soon see the chemical clinic established. If a
problem of liberty is to be solved with machines, and if a problem of
justice is to be regarded from the chemical point of view, similar
consequences will be the logical end of sciences developed upon such
errors.

It is obvious that a real experimental science, which shall guide
education and deliver the child from slavery, is not yet born; when it
appears, it will be to the so-called "sciences" that have sprung up in
connection with the diseases of martyred childhood as chemistry to
alchemy, and as positive medicine to the empirical medicine of bygone
centuries.

I think it will be of interest here to record the impressions of a
person who, leaving the field of mathematics, entered upon the study
of biology and experimental psychology.

It is an account of a young English engineer, who had evidently
mistaken his vocation, and who, after studying my method for two
years, returned to the universities of his own great country as a
student of biology.

This is his opinion of experimental psychology:

In psychology we are studying the most modern experimental
researches. At present we are engaged upon Thought and
Imagination. I must confess that I do not find this course
very illuminating, though I agree that it is necessary to
know something of these researches. In modern psychology
there is nothing at all adequate to the subject of our
method. These investigators seem to me like persons looking
at a tree, and noting the most obvious of its external forms:
the shape of a leaf, a stem, etc., doing all this with great
gravity and using very precise language (perhaps believing
that this constitutes science), but often confusing the
function of _definition_ with that of _description_.

In this manner descriptions of wonderful and fascinating
things are reduced to arid definitions, in order to be
clothed
