Death by curare is relatively slow and horrific, as the victim is awake and aware but cannot move or even speak. However, if artificial respiration is performed until the poison subsides, the victim will survive. Indigenous tribes of the Amazon basin used curare-laden arrows to hunt game for food. Curare does not affect those who eat the animals who were killed by it. A slightly different recipe for curare is used when the intended target is human, such as that used during tribal war. Curare has also been adapted for use as a muscle relaxant during surgery.[Via Mental Floss]
French Garde du Corps du Roi M1814 Officers Helmet
Black varnished leather body and visors trimmed entirely with silver-plated copped fixtures. The body has two large palm leaf scrolls on each side with their curls forward, and the ends terminating behind a silver band that covers the seam between skull and rear visor. The front visor is edged in silver. A large sun ray plate embossed with crown over intertwined scrolls of palms crossing above the face of a deity, all above clouds with a bannered motto "Nec Pluribus Impar" (without comparison under the sun). Screwed to the skull, a crest with feather plume designs on both sides, holds a black chenille of horse hair cropped like a mane and falling forward over the front of the helmet. The ear bosses are sun rays behind the godly face at center, and hold the scalloped, graduating chinscales to the helmet. The chinstraps fasten at the wearer’s chin with a cloth ribbon tie. On the left side, forward to the ear boss, a silver squared tube plume socket holds a two-tiered tulip cup holding the stem of a white cock feather plume. Interior sweatband of leather only. Green color under the front visor and black under the rear visor.
The Garde du Corps du Roi of the King was the senior unit in the Maison du Roi (House of the King). It was disbanded in 1816.
A beautiful gemmy dodecahedral crystal of orange spessartite garnet (seehttp://tinyurl.com/pflvbgr) hangs between two masses of gleaming white crystals of albite feldspar. Also growing out of the feldspar right next to the garnet is a prism of schorl, the traditional name given to black tourmaline. All these minerals grew together out of the stewing remains of a granite, that cooled slowly enough to form large crystals and concentrated the rare elements necessary that didn’t fit into the standard granitic minerals (eg quartz, feldspar, mica). In this case, manganese combined with aluminium and silica, and boron, sodium and iron in the tourmaline.
The specimen in the photo (4.3 x 2.7 x 2 cm) was mined in the famous pegmatites of San Diego county in California (such as the Pala mine). It was mined in the early 1970’s and is held to be a near perfect example of the region’s production. Many crystals from here were etched at some point in their geological history, or damaged by the strong tectonic forces linked to the Pacific plate, but this one remains intact.
