[20] Directions for impregnating water with fixed air, in order to communicate to it the peculiar spirit and virtues of Pyrmont water, and other mineral waters of a similar nature.

[25] The first account of this curious process was, I believe, given in the Mem. de l'Ac. de Sc. de Paris for 1742.

To save the bottle, and to prevent the total loss of the liquor by evaporation, I found myself obliged instantly to carry it down to my cellar.
