Steel manufacture

In 1857, Robert Mushet, an English metallurgist, received a U.S. patent for a method of manufacturing steel which improved the Bessemer process for making steel that would be more malleable. (No. 17,389). His process added manganese in the form of spiegeleisen, an alloy of iron and manganese derived from a Prussian iron ore consisting essentially of a double carbonate of iron and manganese. The softness or hardness of the steel could be regulated by diminishing or increasing the proportion of the triple compound of iron, carbon and manganese. He chose to use the alloy of the Prussian ore because it was more free of sulphur, phosphorus and silicon. Mushet also discovered tungsten steel, an alloy with about 8% tungsten.

A family is at the dinner table. The son asks his father, "Dad, how many kinds of boobies are there?
The father, surprised, answers, "Well, son, there's three kinds of breasts. In her twenties, a women's breasts are like melons, round and firm. In her thirties to forties, they are like pears, still nice but hanging a bit. After fifty, they are like onions."
"Onions?"
"Yes, you see them and they make you cry."
This infuriated his wife and daughter so the daughter said, "Mum, how many kinds of 'willies' are there?"
The mother, surprised, smiles and answers, "Well dear, a man goes through three phases. In his twenties, his willy is like an oak tree, mighty and hard. In his thirties and forties, it is a birch, flexible but reliable. After his fifties, it is like a Christmas tree."
"A Christmas tree?"
"Yes, dead from the root up and the balls are for decoration only."
