In her haste, and in the darkness, she had poured the whole contents of the bottle on the phosphoric cotton, and dropped both without knowing it on a chintz curtain. A fresh evening breeze was blowing in from the window, open behind the shutters, and in one second the curtain was a flaming, waving sheet. Some one sprang up to tear it down, leaping on a table in the window. The table ...

An example of a tribasic acid is phosphoric acid, H{3}PO{4}, and here we may have three different classes of salts of three various degrees of basicity or base-saturation. We may have the first step of basicity due to combination with soda, ...

It is our judgment that the soil thrown into the canals undergoes important changes, perhaps through the absorption of soluble plant food substances such as lime, phosphoric acid and potash withdrawn from the water, or through some growth or fermentation, which, in the judgment of the farmer, makes the large labor involved in this procedure worth while.
