quantity to exhibit the appearance of deliquescence, and might 

 form with it a neutral compound, similar to its alcoate or hy- 

 drate. 



A reason can also be given for the superiority of the aqueous 

 and alcoholic solutions of this chloride over the dry chloride it- 

 self, in absorbing deutoxide of azote. We formerly saw that 

 the alcohol of the alcoate of chloride of calcium was completely 

 expelled by a heat of 250, when no water was present ; but 

 that, when a considerable quantity of water was present, alcohol 

 was retained by that chloride at the temperature of 400 or 500. 

 Now, chloride of iron might be enabled to retain deutoxide of 

 azote more powerfully, by the assistance of alcohol or water, in 

 the same manner. But the retaining power we have formerly 

 found in a similar case to be an index of the absorbing power. 

 Hence solutions of protochloride of iron might absorb deutoxide 

 of azote more powerfully than the chloride itself.
