The interested doctor

A concerned woman phones a doctor and says, "Doctor, I'm worried about my husband. He thinks he's a dog!"

"I'm coming over right away," the doctor says.

When the doctor arrives, the woman opens the door, and her husband, on all four, starts wagging his bottom and licking the doctor's hand.

"Interesting", the doctor says, startled. "I'll examine him. Make him lie down on the sofa."

"Doctor", the woman says, "I can't! He's not allowed the sofa!"

Edmund Cartwright

Born 24 Apr 1743; died 30 Oct 1823 at age 80.In 1784, Cartwright visited a factory owned by Richard Arkwright. Inspired by what he saw, he began working on a machine that would improve the speed and quality of weaving. With the help of a blacksmith and a carpenter, Cartwright produced his power loom, which he patented (1785). The invention revolutionised weaving, changing it from a manual process into a mechanical one. By 1787, he opened a weaving mill in Doncaster. Two years later, he powered his looms with steam engines produced by James Watt and Matthew Boulton. He also invented a machine for combing wool. In 1793 his business failed but parliament recognized his achievements in 1809 with an award of £10,000.
