anhydrate

The hollow on the other side of the cliff became filled with anhydrate gas, and this stopped the operations of the Chinese, who evidently knew of the existence of the mine.

Then there came a European, who knew how the anhydrate gas, being heavier than the surrounding air, settled like water in that terrible hollow.

We must also enter an earnest protest against the importation, upon any terms, of such words as "ironoxydulcarbonate," "ironoxydhydrate," and the adjective "anhydrate."
