A volumetric apparatus is described for the analysis of 200 c.mm. of gas. Simple construction, easy cleaning and handling, and great reliability are the points stressed. The various corrections to be applied in analysis of this kind are fully discussed. The apparatus handles directly samples containing from zero to 100 per cent. absorbable gases. The standard deviation amounts to 0·05‐0·08 vol. per cent. A complete analysis of CO 2 and O 2 requires about 10 min. A method is described for drawing alveolar samples in rabbits.
