What Is This?

When the waitress in a New York City restaurant brought him the soup du jour, the Englishman was a bit dismayed. "Good heavens," he said, "what is this?"
"Why, it's bean soup," she replied.
"I don't care what it has been," he sputtered. "What is it now?"

Jean Charles Marignac

Died 15 Apr 1894 at age 76 (born 24 Apr 1817).Swiss chemist whose life work consisted of making many precise determinations of atomic weights suggested the possibility of isotopes and the packing fraction of nuclei. He began a study of the rare-earth elements in 1840, when barely 23 years old. In 1878, he heated until it decomposed some erbium nitrate obtained from gadolinite. Extracting the product with water he obtained two oxides: a red one he named erbia and a colourless one he named ytterbia. Thus he discovered ytterbium, and later was a codiscover of gadolinium (1880). By separating tantalic and columbic acids, he also proved that tantalum and colubium (niobium) were not identical. The last 10 years of his life he lay prostrate, suffering intensely from heart disease.
