When I was a teenager my Dad told me a story of Doctor Bell which is perhaps apocryphal. Supposedly while serving as an assistant to Bell, Doyle witnessed a memorable example of the doctor's keen abilities as an instructor. Bell was demonstrating to a class of medical students how to detect the presence of sugar diabetes by dipping one's finger into a vat of urine and tasting it for sweetness. He then had each student come forward and duplicate his example. Once the entire class was again seated he informed them that the real purpose of his demonstration was to emphasize the importance of the power of observation. "Had you but paid closer attention to my actions, you would have noticed that I dipped my middle finger into the vat, but tasted my index finger." What student was likely to forget that lesson?
