used at LejTlen for the calculation of Amagat's values at the time. 

 (See Coirmi. 71). In how far we have succeeded in determining 

 the empiric equations may appear from the following tables. We 

 have placed there side by side P, PV{0) — observed pressure and 

 pi-essure X volume — , and PV{C) — calculated with the known 

 volume from the empiric equation; [(J) — {C) the difference between 

 the product PV followiiig from the observation and that following 

 from the foi'mula.
