It will be noticed in the above table that the amounts of both free and albuminoid 
ammonia increased very greatly after four or five days, showing that the fresh albumen, 
like urine, does not yield ammonia so readily as that which is more or less decomposed. 
As the amount of albuminoid ammonia had increased in the ninth and last bottle, a 
larger series would have been more satisfactory.

It will be noticed that the distilled water containing ammonium nitrate yielded 
nearly equal amounts of free albuminoid ammonia all through the series; but when mixed 
with the garden tank water, the free ammonia was reduced very greatly, to about X Y, and 
the albuminoid ammonium to about J in the course of ten days, showing that a great 
change had taken place, due to decomposition or to the action of organisms, or to both.

Note. --On account of the large quantity of organic matter, only 10c. c. of Horse 
Pond water was used in each instance for determination ; this was diluted in retort 
with distilled water free from NH 3 . Used the usual half-litre for Fish Pond water.
