BIOCHEMISTRY Comprehensive study of the properties of solutions in relation to protoplasm together with the physical and chemical laws governing their behavior. The important articles of diet such as carbohydrates, lipides. proteins vitamins, salts, and water are studied in groups, and separately, and chemical tests to distinguish between them and to identify them individually are considered. A study of enzymes and the factors involved In the speed of their reactions upon the several substrates. Salivary, gastric, and pancreatic digestion and all factors involved. The composition of blood is considered and various important functions of blood from a physico-chemical aspect arc studied. A study of the physico-chemical reactions involved in metabolism and energy exchange. A laboratory course correlated with the lectures includes a study of the reactions and behaviors of such materials as amino acids, urea, protein, carbohydrates, and fats. The work of the latter part of the course includes qualitative and quantitative studies of blood, secretions and excretions. A comprehensive study of practical physiological chemistry in which students are required to submit complete reports of their analyses. The relationship to dentistry it paramount. George R. Schactcrlc, B.S.. D-S.C. Robert Rowcn. B.S., Ph.C., Professor of Biochemistry and Dental Materials MATERIALS USED IN DENTISTRY A consideration of dental materials and their manipulation from a physical and chemical standpoint. The general object of the instruction it to familiarize the student with materials that are used in the construction of dental restorations and orthodontic appliances. The effects of the physical forces upon dental materials are studied with an idea of evaluating the substance from a scientific standpoint. Various basic denture materials are studied to deter- John H Githcns BA I) D S mine values and advantages from the standpoint of such properties as strength, resistance to force and erosions, practicability, and appearances. Studies are made on such materials of dental interest at gypsum products, wax. impression substances, cements, porcelains, solders, abrasives, alloys, acrylic resins, etc. The latter portion of the course will be devoted to a study of metals important to dentistry including their sources, methods of extracting them, their physical, chemical, and general metallurgical properties and uses. The manipulations necessary to make them practical from a dental standpoint are a feature of the course. The laboratory course includes determinations of setting time and heat evolution of gypsum products and zinc cements. and the effect of accelerators and retarders on these products. Various solders and alloys are made and tested for melting range, hardness, etc. Dental amalgam alloys are prepared and studied, specimens of alloys are polished, etched and examined to show the effects of heat treatment. 20

ANATOMY-GENERAL Professor of A natomy Richard M. Snodgrassc, Ph.B., MA, Ph.D., Professor of Anatomy The course in General Anatomy is niven throughout the entire freshman year and consists of sixty-four hours of lecture supplemented by one hundred ntnety-two hours of work in the Anatomical Laboratory. The laboratory work is devoted to the study of the gross anatomy of the entire body, whereby each student dissects an entire cadaver giving special attention to the head and neck. Drs. Holland. Whitcomb, Snodgra . But , and J. M. Limquico, A.B., Ph.D.. M.D. Assistant Professor of Anatomy A rose by any other name. i 19

MICROBIOLOGY Instruction it given by meant of lecture and laboratory work in the second temetter of the freshman year. Tlie course of lectures includes an elementary course in microbiology with emphasis on the pathogenic microorganisms and their relation to disease. For the first half of the course, chemotherapy, classification sterilization and bacterial metabolism; for the second half of the course, emphasis on the dental and oral aspect. The application of the basic principles to oral and dental pathology, specific diseases, etiology, diagnosis and treatment. In the laboratory, instruction is given in the principles and their application: preparation of laboratory media, staining methods, biological activities of bacteria and culture techniques. Smears, dark field examinations and electron microscopy are demonstrated. The laboratory course is designed primarily to develop digital skills and sterile techniques. Joseph G McCunncy, Technician Herbert M. Cobe, B.A., M.A.. Ph h p , of Microbiology ' Professor Arthur K. Lebcrknight. B S pkr j Professor of Microhi . ' PhG A“is‘anl of Microbiology HISTOLOGY AND EMBRYOLOGY, GENERAL Maurice L. Leitsch, B.S.. M S., Professor of General Histology and Embryology The subject matter is presented to complete and coordinate the background in anatomy to form a foundation for pathology and other fields of knowledge of significance in the profession of dentistry. The student is given opportunities to develop observational and analytical abilities by means of lectures, demonstrations. assigned readings, and. more especially, by practical studies with the microscope of histological and embryological specimens, some of which he prepares in order to become familiar with microscopic technique. The progress of the student in developing a comprehensive co-ordinated view of the field is determined by objective practical and theoretical examinations. 21
