Pyx.

A box, The word is derived from the Latin pyxis. The Greek word is similar. The box-tree (Latin, buxus) was then, as now, a favorite material for boxes of superior quality, as is evidenced by the common derivation of the name of the thing, and of the material of which it is made. The pyxis of the Greeks and Latins was a jewel-box, and when the great fusion of the two systems took place under Constantine the pyxis became a reliquary.

While the word box has with us a generic signification, the older form of the word pyxis, shortened to pyx, has certain specific meanings:—

1. The box in which the sacramental host is kept in the order of the Roman Church.

2. The box in which sample coins are placed in the English mint. A triannual test by assay for purity is held, and is termed the trial of the pyx. Two pieces are taken from each bag of newly coined money, — one for trial in the mint, the other deposited in the pyx. The Lord Chancellor summons a jury of goldsmiths, who test by weight and assay in comparison with certain standard trial-plates deposited in the Exchequer.

3. The binnacle-box in which a compass is suspended.

4. The acetabulum which receives the trochanter at the head of the femur. [1841]
