    eliminated from the system regularly by rhyth- mically recurring respiration, it would be erro- neous to deny it any further role in the econ- omy of the system. The carbonic acid in our system, with its normal quantitative changes, seems to be necessary to excite important vital functions, especially respiration and circulation. The symptoms of intoxication making them- selves noted at the respiratory pneumogastric and the vasomotor centers when excessive ouan- titles of the gas have been inhaled may be ex- plained, to some extent at least, as suggestions of normal physiological processes. The tension of the carbonic acid in the blood has been calculated in various ways by Pflueger and his pupils, Wolfberg, Strassburg, and Nuss- baum. According to Strassburg, it is 2.8 per cent, of one atmosphere, corresponding to a pressure of 21 mm. of mercury. Nussbaum found in the blood from the right heart a car- bonic-acid tension of 3.81 per cent, of one at- mosphere, corresponding to a pressure of 28.95 mm. of mercury. Bohr, by his experiments on carbonic-acid tension, arrived at other figures. [15]
