We find that where stimulants are required, such remedies as caffeine, nitro-glycerine and kolafra take the place of alcohol, and are even more satisfactory.
Glycerine does not create any craving for itself, and has not been demonstrated to have injurious properties, and is not used for beverage purposes.

In the larger Krupp guns the force of recoil is absorbed by two cylinders, filled with glycerine and fitted with pistons perforated at the edges.
The advantages of the use of glycerine are that in case of a leak it would escape too slowly to lose its effect at once, and it is also more elastic than water, and is less liable to become frozen.
Glycerine thus prepared is a transparent liquid, without colour or smell, and of a syrupy consistence.
