My father's friend Henry used to be a teacher at a medical school and he was very strict to his students. The students were afraid of him though he was seldom pleased with the answers they gave. Once a  student seated before him, and Henry required him to describing a certain illness, his description of which turned out to be OK. Then Henry asked about the cure for the illness, but the student gave the right answer. “How much will you give the patient? ""A full spoor’s!" Suddenly the student realizes that there was anything wrong. He said anxiously,"I've made the mistake：a full spoon is too many, and he can take only five drops." "It's too late；your patient has been died," Henry said coldly.
