milar vessel containing a little distilled water, negatively- 

 electrified by one hundred four-inch plates, charged with a 

 solution of nitro-muriatic acid of the same strength as that 

 employed in a former experiment, fresh portions of water 

 being occasionally added in order to compensate for the loss 

 by its decomposition. 



When the electrization had been carried on in this way 

 for one hour the cups were removed, and their contents 

 examined. 

 In the ne gativt The fluid in the negatively electrified cup acted rapidly

 and subsequent exposure to a low red heat, it afforded a re- 

 siduum weighing 5*5 grains, which had the properties of 

 soda, in a state approaching to purity,

 atic, was held in solution by the water: It gave a very copi- 

 ous precipitate with nitrate of silver, which became speedily 

 black on exposure to light. When saturated with carbonate 

 of soda, and evaporated, it afforded a salt in small cubic 

 crystals, from which the fumes of muriatic acid were deve- 

 loped by the action of the sulphuric. 

 Some muriate This experiment shows, that, exclusive of soda in an un- 

 combined state, fluid albumen coutains some muriate of 

 soda*. We learn from the experiments of Mr. Hatchett, 

 that minute quantities of other saline bodies are likewise 

 present f.
