Excerpt from The Elements of Physiological Physics: An Outline of the Elementary Facts, Principles, and Methods of Physics; And Their Applications in Physiology The modern development of Physiology has been largely due to the application to this branch of science of physical and chemical principles and laws. Physics and chemistry are now constantly appealed to for aid in working out physiological problems; and the physiologist finds himself continually resorting to physical methods and apparatus, both for purposes of illustration and research. In some respects, therefore, the study and the teaching of Physiology have become increasingly difficult because of the broadening of its relations with other sciences. In the teaching of the subject at the University of Glasgow the want has been felt of a small text-book for students, in which the elementary facts and principles of physics might be given together with their physiological applications, and in which might be included some detailed description of physical apparatus and methods as adapted to physiological purposes. To meet this want to some extent, a series of weekly demonstrations was given by me to the students attending the class during the winter months; and one of the results of that series is this text-book.
