Name the animals...

The first-grade teacher was showing pictures of animals to her students to see how many they could name. She held up a picture of a lamb, and a little girl said, "That's a sheep!"

"That's right!" said the teacher. "How about THIS one?" she said, holding up a picture of the king of beasts.

"That's a lion!" answered a little boy.

"Right!" said the teacher. Then she held up a picture of a deer. No one volunteered an answer. She tried to help. "What does your mother call your father?"

Johnny said, "I know! That's a lazy old goat!"

Radiation treatment

In 1896, Émil H. Grubbe, a Chicago researcher, became the first known to administer x-ray radiation treatment for the recurrent breast cancer of a fifty-five-year-old woman. X-rays had been discovered the previous year in Germany. Grubbe tried radiation as a tool against cancer after he suffered a radiation burn while experimenting with X-rays. His experiment didn't cure the woman's cancer, but others in the late 1890s who applied X-rays to various cancers - especially skin cancer - not only relieved cancer pain but actually cured some, which encouraged continued use and study of the X-rays. Grubbe did not publish his work until several years later, and his claims of priority as the first to use radiation treatment were widely doubted.
