PREFACE.

THIS Primer is an attempt to explain in the most
simple manner possible some of the most important
and most general facts of Physiology, and may be
looked upon as an introduction to the Elementary
Lessons of Professor Huxley.

In my descriptions and explanations I have sup-
posed the reader to be willing to handle and examine
such things as a dead rabbit and a sheep's heart;
and written accordingly. I have done this purposely,
from an increasing conviction that actual observation
of structures is as necessary for the sound learning
of even elementary physiology, as are actual experi-
ments for chemistry. At the same time I have
tried to make my text intelligible to those who think
reading verbal descriptions less tiresome than observ-
ing things for themselves.

It seemed more desirable in so elementary a work
to insist, even with repetition, on some few funda-
mental truths, than to attempt to skim over the whole
wide field of Physiology. I have therefore omitted
all that relates to the Senses and to the functions of
the Nervous System, merely just referring to them in
the concluding article. These the reader must study
in the "Elementary Lessons."
