He later wrote "... I can well remember taking a course on Physiological Chemistry given by Professor Hopkins, of Cambridge, in which he referred to Biochemistry as the Cinderella of Physiology. I do not remember what the ugly sisters stood for, but it may have been Histology and Electro-Physiology, because it was at this time that the study of the muscle-nerve preparation of the frog became available for students' class work..."
