[The "standard cell" is a saturated Weston cell, containing an electrode of
mercury in

contact with a paste of mercurous sulfate and an electrode of cadmium
amalgam in

contact with a saturated solution or cadmium sulfate. When little or no
current is drawn

from the cell, it produces a terminal voltage of long-term stability. The
precise value for

each cell is given on its label.]

Any idea what this battery was used for? Found it at a flea market for $1.

The two-piece Bakelite case says The Bristol Company, Waterbury, Conn.
Inside are two glass capsules with different stuff in the bottom. The
bottom
stuff in capsule looks like clay, the other looks like a ball of wrinkled
foil. A sticker on the left capsule says the Eppley Laboratory, Newport,
R.I.

Both capsules still contain liquid. They are cushioned in a tidy little
felt
blanket.
