Here is the /-/-curve sliifted totally to an amount of — 0,8 Erg. 



This is the correction to be applied, and which was already 

 indicated in onr first communication ') ; it has been taken into account 

 since in every case in all the tables. It may here be repealed once more, 

 that although the absolute values of the surface-energy really have 

 approached closer by it to the values formerly published, however 

 the shape of the /-^, or f<-/-curves is not altered by it with respect 

 to any particulai- feature. 



§ 6. Another (luestion to be answered with i-espect to the obtained 

 experimental results, is Ihis, if it may be considered as possible to 

 determine the right values of /, without being embarrassed there- 

 with by the influence of the vlscositij of the studied liquid? For 

 just because the internal friction of liquids always increases rapidly 

 at lower temperatures, and an extreme viscosity of the liquid, — even 

 if the bubbling of the gas is executed with extreme slowness, — 

 will cause, as we have seen, the maximum pressure H to appear 

 too great from all kinds of disliirluug etfects, ■ — • the influence 

 of this viscosity could poihaps be advanced as a cause of such a 

 deformation of the /-^cul•ves, that they just would manifest a steej)er 

 tempei'ature-gra(iient at the low^er leuiperalures than at the higher. 

 Therewith an explanation of the curves of type 3 would be given ; 

 bul il must be here remai-ked already in advance, that suchacnuse 

 could hardly be adopted for the presence of the curves of type 1, 

 just l)ecause all viscosity-curves have themselves ihe shape of type 3, 

 However there seem to be many reasons, not to attribute too high a 

 value to ihis explanation of Ihe curvature of the jj-^lines, even not 

 in the case of type 3. 



In Ihe first place it must be remarked, that Ihe curvature of the
