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.

It says right on it that it is a "Standard Cell". I believe "Standard
Cells" are used for calibrating electrical instruments like voltmeters
and etc. I also believe that they will be damaged by drawing current
from them, so they must be used in special calibration circuits.
