Comprising two cast end pieces, joined by three nickel-plated rods, caring two sliding V-supports for a glass jacket with inlet and outlet tubes.
One end-piece fitted with spherometer reading to 0.005 mm, and the other with contact screw.
The glass jacket enclosed both a brass and a copper rod each 500 x 7 mm length x diameter, fitted through corks , a half turn of the jacket changing rod in contact with the spherometer.
A thermometer can be attached to be either of the rods by rubber bands. Brass terminals are fitted to the apparatus so that an electrical circuit can be made through either rods, to indicate the moment of contact of centre tube and spherometer.
Supplied with 3 metal rods one each of copper, brass and iron.

To show that water has a maximum density at 4 degrees Celsius..
Consists of a sheet metal cylinder with two tubes in the upper and lower regions for inserting thermometers through rubber stoppers. Mounted on a base and encircled midway by an outer trough for holding a mixture of ice and salt. Temperature of the water is measured at the top and bottom of the inner cylindrical vessel over a period as the water-cools.
