In column 8 are found the values of 100 T calculated from g 

 by the aid of the equations (36) and (37), i.e. on the assumption 

 that p =1 1 and q = 4: (see § 13 and fig. 2 curve D). 



In the tirst row the deviation between tiie found and the calcu- 

 lated values of 100 T is again greatest. Much importance should 

 not be attached to this here either, as this deviation -already dis- 

 appears when the glycerine content of the fat is 12.67o instead of 

 12,167o- The other values of columns 7 and 8 agree sufficiently. 



.It is not improbable that also in the autoclave saponitication, 

 where the saponitication takes place in feebly acid surroundings, 

 p^l. Nothing can be said of this, however, with any certainty, 

 as the influence of zinc soap has not been examined in the experi- 

 ments of §§ 7 and 8. If really p = 1 also here, q must have a 

 value which differs little from ^ ^= 4 in virtue of the agreement of 

 columns 7 and 8 of table 1. 



SUMMARY. 



It has been shown in this paper that in the saponitication in 

 emulsion the reaction takes chiefly place on the boundary of the
