Slaked Lime.

This is prepared by burning Carrara marble in a covered crucible until the slaked product no longer effervesces on the addition of Hydrochloric Acid; when cold it is placed in a porcelain capsule, and slaked by the addition of half its weight of distilled water.

The 1 attenuation should be immediately prepared from it as follows: Triturate 1 ounce of the slaked lime with 2 ounces of refined sugar, place the mixture in a bottle and add to it 1 pint of distilled water, cork the bottle and set it aside for a few hours, shaking frequently; separate the clear solution by means of a glass siphon, and add distilled water to increase its bulk by one-half, preserve it in a well-stoppered and capped bottle. Distilled water to which 5 per cent. of rectified spirit has been added is used for 3x, dilute alcohol for 2, and rectified spirit for 5x and upwards.
