itate and lessen the energy of the
circulation, and are thence useful in inflammatory diseases. It must be
added, that if nitre be swallowed in powder, or soon after it is dissolved,
it contributes to lessen the circulation by the cold it generates, like
ice-water, or the external application of cold air.

VI. The respiration of air mixed with a greater proportion of azote than is
found in the common atmosphere, or of air mixed with hydrogen, or with
carbonic acid gas, so that the quantity of oxygen might be less than usual,
would probably act in cases of inflammation with great advantage. In
consumptions this might be most conveniently and effectually applied, if a
phthisical patient could reside day and night in a porter or ale brewery,
where great quantities of those liquors were perpetually fermenting in vats
or open barrels; or in some great manufactory of wines from raisins or from
sugar.

Externally the application of carbonic acid gas to cancers and other ulcers
instead of atmospheric air may prevent their enlargement, by preventing the
union of oxygen with matter, and thus producing a new contagious animal
acid.
