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.

Photography

In 1839, Sir John Herschel referred to “photography” in a lecture to the Royal Society—possibly the first use of the word. Following Henry Fox Talbot's publication of his invention of what became known as the Calotype process, a number of scientific men made their own investigations, including not only Herschel but also Berard, Robert Hunt and Draper. Herschel used the name Chrysotype (from the Greek word for gold) for his process. It used paper washed in a solution of ammonio-citrate of iron and brought out the image with a solution of soda or chloride of gold, or with nitrate of silver, and fixing it in the first case by washing it with iodide of potassium and in the second, with hyposulphite of soda. It had technical difficulties in controlling the contrast, colour and fogging of the image.«*
