1. Apparatus for injecting a substance into a surface, such as the skin of a human being, animal or other organic matter, the apparatus comprising:
- (a) at least one needle;
(b) means for supplying the substance to the tip of the needle;
(c) a driving means for driving the needle at a velocity in the range of 1 meter per second to 100 meters per second in which in use the majority of the energy for penetration comes from the momentum of the needle and associated moving parts and not from the continued force of the driving means.

68. A method for injecting a substance into a surface which method comprises using an injector which consists of at least one needle and a means for supplying the substance to the tip of the needle in which method the needle is placed against the surface and the end of the needle struck by an impact to drive the needle into the surface at a velocity in the range of 1 to 100 meters per second and the substance supplied to the tip of the needle to inject the substance into the surface.
