Snake wood

The ordinary European snake-wood oil is distilled from the root of A arwn europaevm, which yields about 1 per cent, of a thick dark brown oil of sweet aromatic odour. The specific gravity of this oil varies from 1-015 to T07. According to Petersen, when frozen it de-pofflts crystals of asarone. 

The groundwater geochemistry of the Snake River Plain aquifer system has been described by Wood and Low (1988). It is an excellent example of how a knowledge of aquifer mineralogy can...

These snakes occupy a variety of habitats including pond and stream edges, wetlands, forests, fields, rocky hillsides and residential areas. They are often observed as they bask on rocks, wood piles, stone walls, and hedges. Although they feed on a variety of small animals, primary prey are earthworms and amphibians. 

One of the earliest examples of chemical warfare was in the late Stone Age (10,000 BCE). Hunters known as the San, in southern Africa, used poison arrows. They dipped the wood, bone, and stone tips of their arrows in poisons obtained from scorpion and snake venoms, as well as poisonous plants (CBW Info, 2005 Tagate, 2006 Wikipedia, 2007a). 

If we are in a wood and see a stick that might possibly be a snake we are better reacting immediately as if it were indeed a snake. However ... 

Snakes — Snakes tend to be found near rocks and wood piles. Most snake bites are below the knee, therefore, tall leather boots are useful preventive footwear. If you do get bit ... 

Eccentricity, Hough transform, snakes. Give information on general shape or whether a particular shape is present (Gonzalez and Woods, 2002). 

Clearly, first-aid kits should be tailored to their specific uses. If you live in an urban area, you probably don t need a snake-bite kit in your bathroom. You might, however, need one if you live in or near the woods or to stock your hiking...
