Electric discharges; Scientific apparatus and instruments
When connected to a power source, a bright electric spark would flash between the two ends of the two outer posts. The middle glass post is made of photo gray glass (yellow tinted glass), which would have glowed. This instrument is visible in early...
Electric discharges; X-ray tubes; Scientific apparatus and instruments
This instrument appears to be an early type of vacuum discharge tube or x-ray tube. The glass tube contains metal electrodes that have been sealed and from which the air has been removed by a vacuum system. Physical Description: Glass bulb with...
Galvanometer; Scientific apparatus and instruments
A galvanometer is an instrument used to measure the presence, direction, and strength of small electric currents in a conductor. A magnetic needle is deflected by the presence of an electric current in a nearby conductor. The needle turns at right...

The Oersted Piezometer was used to determine the coefficient of the compressibility of liquids. Gases would have been pumped into the chamber through the funnel at the top. The pressure of the gases would have been measured via the water barometer...
Crova's apparatus was designed for the purpose of representing vibratory movements on the screen, with 8 disks. Turning the crank past a vertical slit caused the disks to rotate, while a beam of light from the optical system impinged on the slit...
"This unique piece of apparatus uses Lissajous figures to show that the ratio of the frequency ratios in a diatonic scale are ratios of small numbers. On the side is an air-driven vibrating reed with a small mirror attached to its free end....
