Bill, Jim, and Scott were at a...

Bill, Jim, and Scott were at a convention together and were sharing a large suite on the top of a 75-story skyscraper. After a long day of meetings they were shocked to hear that the elevators in their hotel were broken and they would have to climb 75 flights of stairs to get to their room. Bill said to Jim and Scott, let's break the monotony of this unpleasant task by concentrating on something interesting. I'll tell jokes for 25 flights, and Jim can sing songs for 25 flights, and Scott can tell sad stories the rest of the way. At the 26th floor Bill stopped telling jokes and Jim began to sing. At the 51st floor Jim stopped singing and Scott began to tell sad stories. "I will tell my saddest story first," he said. "I left the room key in the car!"

Nehemiah Grew

Baptized 26 Sep 1641; died 25 Mar 1712 at age 70. English botanist, physician, and microscopist, who was one of the founders of the science of plant anatomy. He began observations on the anatomy of plants in 1664, and his first essay on the subject, The Anatomy of Vegetables Begun was presented to the Royal Society of London in 1670 (published 1672). He took a particular interest in determining the physiological nature of the tissues. He observed the pourous structure of plant tissue, suggested that flowers have a sexual function, and was first to use the term "comparative anatomy" (1676, in a lecture at the Royal Society). His extensive studies of plant tissues, including roots, trunks, leaves, flowers, fruits and seeds were published in a major work The Anatomy of Plants (1682). From a chemical analysis of water from springs at Epsom, Surrey, he isolated magnesium sulphate, which remains known as "Epsom Salts."
