2013.3.61Description
This is an instrument for measuring the compressibility of liquids.
We have only one example of this interesting device and it is not complete since it lacks the inner thermometer, the bulb, and the tube. The exterior tube is made of exceedingly heavy brass and glass, and weighs about 20 pounds. Hans Christian Oersted (1777-1851) was a professor at Copenhagen. He is also credited as the real discoverer of the magnetic properties of electric currents.
This apparatus probably was purchased by Dr. Peter from Deleuil, Paris, in July 1839 for 65 francs.Collection
