cultivation. The questions for review, or any others that the wit of the
teacher may suggest, can be effectively used to break the monotony of a
topical recitation, thereby securing the benefits of both systems.

The pupil should expect to be questioned each day upon any subject passed
over during the term, and thus the entire knowledge gained will be within
his grasp for instant use. While some are reciting to the teacher, let
others write on slates or on the blackboard. At the close of the
recitation, let all criticise the ideas, the spelling, the use of
capitals, the pronunciation, the grammar, and the mode of expression.
Greater accuracy and much collateral drill may thus be secured at little
expense of valuable school time.

The Introduction is designed merely to furnish suggestive material for the
first lesson, preparatory to beginning the study. Other subjects for
consideration may be found in the section on Health and Disease, in the
Selected Readings, and among the questions given in the Appendix. Where
time will allow, the Selected Readings may profitably be used in
connection with the topics to which they relate. Questions upon them are
so incorporated with those upon the text proper that they may be employed
or not, according to the judgment of the teacher.

NOTE.--Interest in the study of Physiology will be much increased by the
use of the microscope and prepared slides. These may be obtained from any
good optician.

INTRODUCTION.

Physiological study in youth is of inestimable value. Precious lives are
frequently lost through ignorance. Thousands squander in early years the
