Experimental Work in Physiology.

406. The Limitations of Experimental Work in Physiology in Schools.
Unlike other branches of science taught in the schools from the
experimental point of view, the study of physiology has its limitations.
The scope and range of such experiments is necessarily extremely limited
compared with what may be done with the costly and elaborate apparatus of
the medical laboratory. Again, the foundation of physiology rests upon
systematic and painstaking dissection of the dead human body and the lower
animals, which mode of study very properly is not permitted in ordinary
school work. Experiments upon the living human body and the lower animals,
now so generally depended upon in our medical and more advanced scientific
schools, for obvious reasons can be performed only in a crude and quite
superficial manner in secondary schools.

Hence in the study of physiology in schools many things must be taken for
granted. The observation and experience of medical men, and the
experiments of the physiologist in his laboratory must be depended upon
for data which cannot be well obtained at first hand by young students.

407. Value of Experiments in Physiology in Secondary Schools. While
circumstances and regard for certain proprieties of social life forbid the
use of a range of experiments, in anatomy and physiology, such as are
permitted in other branches of science in secondary schools, it by no
means follows that we are shut out altogether from this most important and
interesting part of the study. However simple and crude the apparatus, the
skillful and enthusiastic teacher has at his command a wide series of
materials which can be profitably utilized for experimental instruction.
As every experienced teacher knows, pupils gain a far better knowledge,
and keep up a livelier interest in any branch of science, if they see with
their own eyes and do with their own hands that which serves to illuminate
and illustrate the subject-matter.
