When the St. Louis, Arkansas and Texas line was built from Corsicana to Milepost 35 in 1887, the station, called Mertens for the wife of the engineer on the first train, was built near the Walling place.
Fluorescence is the emission of light or photon, similar to bioluminescence and phosphorescence. However, each of them differs beyond the atomic level. Bioluminescence is when an organism emits light through biochemical means. Bioluminescence is the outcome of the oxidation of luciferin and the enzyme luciferase.
Fluorescence literally is the emission of light from an object as the reaction to a radiation of light from one other source. In a diamond, the presence of fluorescence essence is created by a natural development of the mineral itself that, during the process of crystallization develop this luminescence.
