"Frame 9 - Mr. Yü Fu-Hsin, our senior laboratory technician, is the member of the Medical School staff with the longest record. Disqualified as a medical student because of the handicap of deafness, he found a profession in which it proved an asset. He has studied and taught most of the subjects in the first two years of the medical course and has trained many generations of medical students and technicians during his thirty years of service, and perennially retains his patience and enthusiasm for teaching. He is seen here, reading a Kahn precipitation test. All the standard serologic tests for syphilis are performed in his laboratory, and also one which he devised, in collaboration with a colleague." A Chinese man in a lab coat is examining various vials and writing down observations in a notebook.
