“ A course in physiological chemistry worthy of the name should extend. Professor Chittenden thought, at least through half the college year, and preferably through a whole year, with an average of fifteen hours of laboratory work a week, interspersed with lectures, recitations, and demonstrations. It could be advantageously undertaken only by men who already have knowledge of general, analytical, and organic chemistry, physics, anatomy, and histology, together with more or less familiarity with general physiology. ”

“ So, too, in every well-rounded biological course there should be ample facilities for instruction and experimentation, not only in pure physiology but likewise in physiological chemistry, so that a broader and clearer conception of physiology may be obtained than is possible by the presentation of a single side of the subject" Professor Chittenden has labored faithfully to embody the principles expressed in these views and give them practical effect in the work of the biological course at Yale University. ”

“ The existing laboratories of chemistry, physics, zoölogy, and botany at Yale had made it easy to establish a course in general biology at this time, well adapted for providing instruction in branches especially fitted for men intending to enter the medical profession, but in which facilities in physiology and physiological chemistry were still almost wholly wanting. ”

“ In estimating the value of the various aspects of the study, it is shown that our knowledge of the composition of the tissues, organs, and fluids of the organism is derived entirely from chemical study and investigation. ”

“ Morphology, comparative anatomy, general biology, botany, zoology, etc., are by no means ignored, but physiology and physiological chemistry have been made an integral part of the instruction in biology given to the undergraduate students in the Sheffield Scientific School. ”

“ One of the most advantageous of these courses has been preliminary to medicine. To follow the healing arts, which have made during the last half century such wonderful advances, discipline is requisite in physics, chemistry, and physiology with prolonged laboratory practice and increasing familiarity with the normal functions of organic life. ”

“ Naturally, the majority of the students electing this course of study, extending through two years of the college course, are intending to enter upon the study of medicine after graduation, and it is interesting to note that the graduates of this course almost invariably take a high standing in their professional study, thereby indicating the beneficial effects of their biological training. ”
