Types of Bears

A married couple was vacationing in Yosemite Park in the United States. The wife expressed her concern about camping because of bears and said she would feel more comfortable in a motel. The husband said he would like to camp outside in the woods. To calm her concerns, he suggested they talk to the park ranger to see what the likelihood of a bear encounter would be.

The ranger told them, "Well, we havewn't seen any grizzlies in this area so far this year, or black bears, for that matter."

The wife shrieked, "There are TWO types of bears out here? How can you tell the difference? Which one is more dangerous?"

The ranger replied, "Well, that's easy -- see, if the bear chases you up a tree and it comes up after you, it's a BLACK bear. If it SHAKES the tree until you fall out, it's a grizzly."

The motel room was quite nice.

Ovariotomy

In 1809, the first U.S. ovariotomy (the surgical removal of an ovarian tumour) was performed at his Danville, Ky. practice by Dr. Ephraim McDowell (1771-1830), the “Father of Ovariotomy.” A few days before, on 13 Dec, he had travelled 60 miles to the house of Jane Todd Crawford, 45, in Motley's Glen, Kentucky. She had been previously attended by less skilled practioners who had first thought she was pregnant with twins. McDowell instead diagnosed a huge tumour. After she was transported to his surgery, McDowell operated, and removed a 22-pound ovarian tumour - in an era that had no anaesthetic. She quickly recovered, and lived to be 78. His published account (1817) of the operation created a sensation. He performed eight more ovariotomies, the last in 1826. His statue stands in the U.S. Capitol.«
