Observations on Table XVI. — Ammonia. 



The table of ammonia is calculated on the following prin- 

 ciples : — The atom of water is assumed to weigh 112*5 grs., 

 and to measure 16*071429 septems. The atom of ammonia 

 is assumed to weigh 212*5 grs., and to measure 42*857143 

 septems. The relation of these measures is as follows : — 



16*071429 X -| = 42*857143. 



The ammonia and water are assumed to combine together in 

 all cases without any alteration of measure. The composition
