Calorimeter. This apparatus which seems an anticipation of the Favre-Silbermann calorimeter is unknown in Lavoisier's published writings. A cubical wooden box, on a wooden base, evidently formerly covered with tin foil, inside and out, is open at the top. From one face of box rises a wooden strip, graduated from 50 to 63, each division being divided into ten parts. Against this strip is fixed a capillary tube, terminating at the top in a sperical bulb with a neck fitted with a rougly cut wooden stopper. The box contains a glass bulb which has been broken from the lower end of the capillary tube |
