The determination of the free acids was in this case made seven months 

 after the other determinations. The lards in the meantime were kept in stoppered 

 glass bottles in an ice-box. 



These analyses show very remarkable variations from the usual lard constants. 

 For lack of data no conclusions regarding the cause are attempted. 



In order to determine if the native, domestic hogs all showed the same 

 peculiarities in their fats, three samples of lards were obtained at the 

 slaughter house from a freshly killed hog of unknown origin, and a 

 composite sample of fat was taken from three different hogs.
