This may be effected in a rariety of ways, one of the most convenient of which is by means of a vessel con- taining some saturated sodium carbonate or similar solution in connection with the manometer. It is important that the pressure should express itself as directly and truthfully on the mercury of the manometer as possible, hence the employment of a tube with ri«rid walls, yet capable of being bent readily in different directions for the sake of convenience. Mercury, on account of its inertia, is not free from objec- tion; and when very delicate variations in the blood-pressure— . I. 196.—LwsekyiiMcnplitWitkcoiiUniiou toll of paper (IVMtOT).
