144     Although equal parts of alcohol and freshly expressed juice are usually the most suitable proportion for affecting the deposition of the fibrinous and albuminous matters, yet for plants that contain much thick mucus (e.g., Symphytum officinale, Viola tricolor, etc.), or an excess of albumen (e.g., &Aelig;thusa cynapium, Solanum nigrum, etc.), a double proportion of alcohol is generally required for this object. Plants that are very deficient in juice, as Oleander, Buxus, Taxus, Ledum, Sabina, etc., must first be pounded up alone into a moist, fine mass and the stirred up with a double quantity of alcohol, in order that the juice may combine with it, and being thus extracted by the alcohol, may be pressed out; these latter may also when dried be brought with milk-sugar to the millionfold trituration, and then be further diluted and potentized (v. § 271)
