The cylinder A is tilledwith water, and thus protects the gas from changes of temperature. Thi ir substance to be analysed, is placed in the bottle Cj the small india- test tub- r, tilled with IKI, is next introduced carefully, and the bottle closed by means of the stopper,. so as to bring the acid in contact with the substance;by opening the clip P the water can le brought to thesame level in A ami B.
