In the late Dr. Abbott's museum of Egyptian Antiquities, New York City, are three of the ancient cupping-horns, similar to those used through the East at the present time.
The operator exhausts the air through a small hole at the point of the horn, to which he applies his mouth, and then covers it with a piece of leather, which is attached to it for that purpose.
They were found in tombs at Sakkarah.
Cupping-instruments are described by Hippocrates 413 B. C., and by Celsus 20 B. C.
Hero of Alexandria states that the instrument is intended to be used without fire, referring to the practice then in vogue of rarefying the air within the tube as a means of obtaining a partial vacuum.
The cupping-glass (A, Fig. 1552) described by Hero, has an outer chamber with an open mouth a, and an inner chamber b, divided from the former by a diaphragm f; m is a valve which governs the opening e in the diaphragm; the valve d governs the opening c by which the chamber b is connected
