There is a large class of substances which are added to food for the
purpose of giving it flavour, and which on account of the volatile oils
they contain act as stimulants. These substances are known as Spices and
Condiments. They also serve as the basis of a large number of sauces,
which are sold ready prepared for the purpose of being added to cooked
food. There is some difficulty in separating Spices from Condiments, but
the former are more generally eaten with sugar, the latter with salt.
In Cases 40 to 43 will be found an extensive series of Spices and
Condiments from various parts of the world.
