Lunge's Gas Volumeters. (Illustrations see page 677.) 



These apparatus, which constitute an important improvement in the manipulations connected with gas 

 analysis, and especially provide for dispensing with the calculations necessary for temperature and pressure, 

 have been designed by Lunge. See Journal of Society of Chemical Industry, May, 1890, p. 547. Two forms are 

 illustrated in this abstract of Lunge's paper, but we subjoin illustrations of the other forms, with a reference to 

 the special work for which they are adapted. 



For a detailed description of these apparatus see Berichte der Deutschen Chemischen Gesellschaft, No. 4, 1890, 

 Zeitschrijt fur Angeivandte Chemie, 1890.
