The workers in a large office...

The workers in a large office were making secret plans to stage a big office party for the 70-year old cleaning woman who had spent the better part of her life with the company.
Somehow the secret leaked out and the woman got wind of it. Much perturbed, she rushed to the office manager. "Please sir," she cried, "Do not let them do it! Do not let them do it!"
"Oh, come now, Mrs. Smith, you must not be so modest. After all, they simply want to show how much you are appreciated."
"Appreciated, my foot," exclaimed the woman. "I am NOT going to clean up after a mess like that!"

Iodine discovery announced

In 1813, a new substance - iodine - was announced at the French Institute by Nicolas Clément, in the name of its discoverer, Bernard Courtois. In 1811, Courtois had observed violet crystals with a metallic lustre that condensed from the vapour rising from the mother liquor of seaweed ash being leeched in sulphuric acid at his family's saltpetre business in Dijon. Although he made a preliminary investigation of this substance, he lacked the resources to fully research it. For this he turned to C.B. Desormes and Nicolas Clément. They suspected the substance was similar to chlorine, but confirmation of its nature as an element was made independently by Joseph-Louis Gay-Lussac, who named it iode, and Humphry Davy (1814).[Ref: Clément, N., Découverte d'une Substance Nouvelle dans l'Vareck par M.B. Courtois. Ann. Chim., 88, 304-310, 1813.] [Image: iodine crystals deposited from vapour on a col glass surface.]
