CARBoNIC ACID AS A THERAPEUTIC AGENT
Joseph Hrsh In paper lately read before the Chicago
College Of Pharmacy, gives an account Of series OF exc
perments made by him, showing the power Of caroola
acid 10 coaguae albumen and adds some remarks upon
the effect OF this acid the human system the import
ance Of which can hardly be oyerestmaed The appi-
