Chapter 32

Note 46, page 124: Bichloride of mercury is a strong antiseptic, and much favored for disinfecting dishes and other vessels used by sick people. It is convenient to carry, in a form known as Bernay's tablets. They come white or blue, and one is dissolved in water to make a solution. They are very poisonous, internally, and Scouts must look out that none of the solution enters the stomach. Of course, there are many antiseptic substances for washing wounds: potash and borax are good, especially in the form of potassium permanganate and boric acid. Anything in a tablet or a powdery form is easier to pack than anything in a liquid form. Wounds must be kept surgically clean, which means "aseptic" or perfectly free of poisoning microbes, or else there may be blood-poisoning. So Scouts should be careful that their fingers and whatever else touches a wound also are surgically clean, by being washed well in some antiseptic. Cloths and knife blades, etc., can be made clean by being boiled for ten minutes.
