After a while, he looked into his pocket to see how the frog was doing.The frog said again, “Mister, I’ve had a spell cast on me. If you’ll kiss me, I’ll turn into a beautiful princess and I’ll make you happy for the rest of your life.”The preacher just smiled and kept on fishing. When he checked on the frog again, it said, “What’s wrong with you, fella? I said I’ve been bewitched. Just kiss me and I’ll turn back into a beautiful princess and make you the happiest man on earth for the rest of your life!”The old preacher just smiled and said, “Frog, I’m sorry to tell you this…but at my age, I’d rather have a talking frog than a beautiful princess!”

Carl Gustaf MosanderDied 15 Oct 1858 at age 61 (born 10 Sep 1797).Swedish chemist and mineralologist; whose work revealed the existence of numerous rare-earth elements with closely similar chemical properties. In 1839 he discovered lanthanum (La) which is used as a component of misch metal (used for making lighter flints) and rare-earth compounds containing lanthanum are extensively used in carbon lighting applications, especially by the motion picture industry for studio lighting and projection. He discovered other rare earth metals: erbium (Er) in 1842 and terbium (Tb) in 1843. Erbium oxide is rose-pink, and it is used to make pink glass and pink potter's glaze. Terbium oxide has potential as an activator for green phosphors used in colour televisions tubes.[Image: Lanthanum ore.] |
