To clean Palette and Brushes.
The palette and brushes must be washed quite clean after daily use, with spirits of turpentine. If the paint is allowed to harden (as it will in a few hours), it cannot be removed.
Health.
For the preservation of health, this description of illuminating should, in summer, be carried on with widely-opened windows, and in winter beside a large fire, which purifies the air of the room, and prevents the smell of the turpentine, &c. from being injurious to delicate persons.
Colours for Special Seasons.
Advent.
For the season of Advent, violet ground, with red and white letters.
Lent.
For Lent, a warm or pinkish-grey ground, letters all white, with black edges.
