vilization, since it enables us to advance rapidly toward perfection
all sciences and forms of knowledge now known, and to introduce new
sciences heretofore unknown.

1. To the MEDICAL COLLEGE it will give a method of accurate diagnosis
which will supersede the blundering methods now existing--a method of
RAPIDLY enlarging and perfecting the materia medica--a method of
exploring all difficult questions in Biology and Pathology, and a
complete view of the constitution of man.

2. To the UNIVERSITY it offers a method of revising and correcting
history and biography--of enlarging our knowledge of Natural History,
Geology, and Astronomy, and exploring Ethnology.

3. To the CHURCH it offers a method of exploring the origins of all
religions, the future life of man, and the relations of terrestrial
and celestial life.

4. To the PHILANTHROPIST it offers the methods of investigating and
supervising education and social organization which may abolish all
existing evils.

The foregoing were the initial steps and results in the development of
Psychometry, simultaneously accompanied by those other discoveries in
1841, the scope and magnitude of which appear to me and to those who
have studied my demonstrations, to be far more important than anything
that has ever been discovered or done in Biological science, being
nothing less than a complete scientific demonstration of the functions
of the brain in all its psycho-physiological relations. To appreciate
their transcendent importance, it is necessary only to know that the
experiments have been carefully made, have often been repeated during
the past forty-five years, and that all they demonstrate may also be
demonstrated by other means, and fully established, if no such
experiments could be made.

The origin of this discovery was as follows. My advanced
investigations of the brain, between 1835 and 1841, had added so much
to the incomplete and inaccurate discoveries of Gall, and had brought
cerebral science into so much closer and more accurate relation with
cerebral anatomy and embryology, as illustrated by Tiedemann, that I
became profoundly aware of the position in which I found myself, as an
explorer, possessed of knowledge previously quite unknown, and yet, at
the same time, however true, not strictly demonstrable, since none
could fully realize its truth without following the same path and
studying with the same concentrated devotion the comparative
development of the
