Paintings

An artist asked the gallery owner if there had been any interest in his paintings currently on display.
"I've got good news and bad news," the owner replied. "The good news is that a gentleman inquired about your work and wondered if it would appreciate in value after your death. When I told him it would, he bought all 15 of your paintings."
"That's wonderful!" the artist exclaimed, "What's the bad news?"
With concern, the gallery owner replied, "The guy was your doctor."

Daniel Quare

Died 21 Mar 1724 (born c. 1648).English clockmaker who was one of the most eminent of his time, with wealthy clients for his clocks, barometers and mathematical instruments. In 1680, he invented a repeating pocket watch mechanism which struck the nearest hour and quarter hour on a bell inside the case when a pin was pushed, thus giving the time even in the dark. On 2 Aug 1695 he received a patent for a portable weather-glass (barometer) which "may be removed and transported to any place, though turned upside down, without spilling one drop of the quicksilver, or letting any air into the tube." Quare's elegant barometers had a wooden or ivory column resting on brass feet, with a brass compartment with a glass front to read the measurement scales at the top of the barometric tube.«[Image: Repeating pocket watch by Quare, circa 1700]
