Diachylon (litharge or lead plaster) is made by boiling olive oil nine parts, litharge five parts, water two parts, over a slow fire, and constantly stirring, until the oil and the litharge unite, and acquire the consistence of plaster. The water must be replaced as it evaporates. Diachylon is an ingredient in sticking plaster and charges, and is useful when spread on leather, for defending a tender part from pressure.

When after skimming it for ten minutes, put in the gut or hair for about a minute (stirring it round), or until you like the colour. If it continues too long, it will become quite dark and injure the hair. The lighter it is tinged with this colour, the better. Salt and ale will also give hair a brownish cast that is steeped in it. * * * * * For a blueish water colour, proceed as above; only add logwood instead of the walnut, and be careful not to colour it too much. * * * * * _Yellow._—The inner bark of a crab-tree boiled in water with some alum, makes a fine yellow, which is excellent when the weeds rot, the line appearing of the same hue. Another dye may be obtained from two quarts of small ale, and three handfuls of walnut leaves bruised therein; the hair to remain in it until tinged to your wish. * * * * * _Tawny_ is prepared from lime and water mixed together, by steeping hair in it for four or five hours, and then soaking it a whole day in a tan pit.
