A per cent solution of sodium carbonate is used to dissolve thestroma of the erythrocytes and so render the blood solution perfectlyclear. If this is not done the color of the blood solution invariably ap-pears darker in tone than that ofthe colored glass wedge. A freshlyprepared sodium carbonate solu-tion should be used in order thatthe clearness of the solution maynot be marred by the presence ofsodium bicarbonate. 3. Dares Hemoglobinometer(Fig. 92).—This instrument, asthe name signifies, is used for thedetermination of hemoglobin. Inusing either Fleischls hemometeror the instrument as modified byMiescher the blood is diluted forexamination, whereas with theDare instrument no dilution is re-quired. This probably allows ofrather more accurate determina-tions than are possible with theold Fleischl apparatus. The instrument c
