a subject
that has been badly neglected throughout the centuries.

It has been determined that the entire human body consists of a certain
number of chemical elements, appearing in different aggregations in
different parts. These aggregations repeating themselves in the various
organs.

Twelve principal aggregations of chemical elements have been established
and designated by the term _tissues_.

This fact led to the discovery of the truth that in the process of
healing attention must be given, not to the various organs, but to the
various tissues.

These tissues are dependent directly upon the condition and contents of
the blood, whose office it is to nourish them and which exhibits the
wonderful property of conveying to each tissue its selective
regenerative materials, _provided of course, that these elements are
present at the time in the blood_.

Sixteen definite elements have been established--and a seventeenth will
probably soon be added thereto--which, in their various combinations and
aggregations, form the different tissues of which the organs in the
human body are composed.

The prevalence of one or several of these elements in a certain tissue
forms the main or governing feature of that tissue. Thus, the prevalence
of potassium phosphate characterizes muscle tissue, the prevalence of
ammonium phosphate (lecithin) nerve tissue. Each one of the various
tissues consists of certain of these elements, and each tissue at every
point where it occurs is affected by the lack of any of its elements.

One of the greatest physiological chemists, Justus von Liebig, maintains
that, if one of the necessary elements in a chemical composition is
missing, the rest cannot fulfill their duties and the respective cells
must become diseased and degenerate.

This discovery, known as "the law of the minimum," has thrown additional
light upon the tasks before the new school of medicine.

Upon the basis of a careful diagnosis, the necessary nutritive salts or
cell-foods, carefully compounded in accordance with the law of
chemotaxis must be administered. This law discovered by _Engelmann_,
requires that these cell-foods must be administered in digestible and
assimilable forms so that the cells will be attracted by the chemical
reaction, which may be of a positive or a negative character.

This being so, we can easily build up the tissues, by studying their
chemical composition and supplying to the system that which is
nece
