Let's review. An ephelis, or freckle, is a type of macule, which is a small (up to 1cm in diameter), circumscribed, flat, and thus nonpalpable change in the pigmentation of the skin. By nonpalpable, I mean you can't feel it. Or more specifically, you can't feel any difference between it and the surrounding 'normal' skin.
The troy ounce is the standard silver price that you see on the t.v. 1 troy ounce = 31.1034768 grams or 1.09714 U.S. Ounces. It is usually just referred to as an oz.
