- Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists at standard conditions as a semi-lustrous, non-metallic solid that melts to form a deep violet liquid at 114 °C (237 °F), and boils to a violet gas at 184 °C (363 °F). The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac, after the Ancient Greek Ιώδης ‘violet-coloured’.
- Lewis County — Thumbnail History (historylink.org)
Lewis County in southwest Washington can truly be called the “mother of counties.” Half of the present-day Washington and of British Columbia were carved from its original borders. But the county’s location astride the Cowlitz Trail between the Columbia River and Puget Sound meant that communities with good water access would develop first. The construction of the transcontinental railroad in the 1870s and innovations in logging technology were the major spurs to settlement.
