The following results were recorded : —

The particulars of the experiments are recorded in the subjoined Table 



Table IX. 



So far as the relationships between the quantity of organic nitrogen originally- 

 present in a water, and that of the inorganic nitrogen which finally results from 

 its complete fermentation are concerned, the above results do not do more than 

 afford additional evidence of the general conclusions which those of the preceding 

 experiments have yielded, viz. that much the greater portion of the fermentable 

 organic nitrogen in a water, is converted into inorganic nitrogenous bodies. It is 

 impossible, it is to be feared, to obtain more accurate results, with the present 

 known method for the nitrogen determinations, whereby any more definite 

 inference as to this relationship can be drawn than the general one just given, 

 since the errors attending the various determinations required become very much 

 too appreciable. 



Notwithstanding, however, this want of precision in the nitrogen determina- 

 tion, the experimental details quoted in the above Table IX., when considered
