JOLLY, etc.). J For Berlin, calculated by W. Lasch (Chem. Pharm. Centralbl., 1852. p. 148. § The specific weights here given are calculated from the equivalents used in the German edition and are based on the specific weight of oxygen, 1 . 10563, as determined by REGNAULT. II Sulphur vapor has not this specific weight below 800° to 1000°; at 450° to 500° it is 6.6. 1 The values of hydrogen, carbonic acid, and nitrogen as determined by REGNAULT are given for comparison with the calculated values. From these the weights of a litre of the different gases at Berlin are reckoned, taking the weight of a litre of atmospheric air in Berlin as the standard. TABLE VII. 1213 TABLE VIT.

CRAFTS found no important difference between the two kinds of glass; the differences between his values and those arrived at by REGNAITLT and others are accounted for by him from the circumstances that the composition of the glass of which thermometers were formerly made was very different from that of the glass now employed for this purpose.
