A group of third, fourth and f...

A group of third, fourth and fifth graders accompanied by two female teachers went on a field trip to the local racetrack to learn about thoroughbred horses and the supporting industry.
During the tour some of the children wanted to go to the toilet so it was decided that the girls would go with one teacher and the boys would go with the other.
As the teacher assigned to the boys waited outside the men's toilet, one of the boys came out and told her he couldn't reach the urinal. Having no choice, she went inside and began hoisting the little boys up by their armpits, one by one.
As she lifted one, she couldn't help but notice that he was unusually well endowed for an elementary school child.
"I guess you must be in the fifth," she said.
"No ma'am," he replied, "I'm in the seventh, riding Silver Arrow. Thanks for the lift anyhow."

Thyroxine

In 1914, the thyroid hormone, thyroxine, was first crystallized by biochemist Edward C. Kendall of the Mayo Foundation in Rochester, NY. Thyroxine controls the cellular rate of carbohydrate metabolism and of protein synthesis and breakdown. On Dec 23, he began evaporating an ethanol solution of a sample of the acid-insoluble fraction of thyroid glands removed surgically from patients. It left a white crust surrounded by a ring of yellow waxy material. Adding ethanol now redissolved the waxy material, but not the white crust. On Christmas Day, he dissolved some of the white crust in ethanol and sodium hydroxide. A few drops of acetic acid precipitated crystals. This throxine was fully active in relieving the symptoms of thyroid deficiency in hypothyroid patients.
