EXPERIMENTS IN DEFECATION. 323 



Besides the experiments in defecation just recorded, and preliminary 

 to them, the following experiTneuts were made in the laboratory, 

 with comparatively small quantities of juice, for the purpose of learn- 

 ing the effects of various defecating agents, especially lime, sulphurous 

 acid, and sulphite of lime. 



The results of these experiments are given in the following table, as 

 being chiefly valuable to those who may desire to continue investiga- 

 tions in the same direction. 



In each case a sample of juice was analyzed as usual, and then sepa- 

 rate portions of this juice were submitted to different modes of treat- 

 ment, and the resulting products were in each case fully examined, and 

 the gain or loss of sucrose, glucose, and solids resulting from the sev- 

 eral methods of defecation, were thus shown.
