    EXPLANATION OF FIGURES. PLATE XXII. Fig. 1. A. Trace with blood mixture. B. Trace taken ten minutes after the substitution of blood mixture by 200 c.c. of saline solution containing 2 c.c. of 1*685 per cent, of caesium chloride. C. Ten minutes after the addition of 3 c.c. of a 1 per cent, solution of sodium bicarbonate to 150 of the above. D. After the addition of 1 c.c. of a 1 per cent, solution of potassium chloride to 150 of circulating fluid and subsequently of 1*5 c.c. of a 1*586 per cent, solution of strontium chloride. E. After the addition of 1*5 c.c. of a 1*11 per cent, solution of calcium chloride. Fig. 2. A. Trace with blood mixture. B. Trace about fifteen minutes after replacing blood mixture with 200 c.c. saline solution containing 4 c.c. 1 per cent, solution of sodium bicarbonate and 2 c.c. 1*11 per cent, solution of calcium chloride. C. Trace five minutes after adding 2 c.c. of 1*685 per cent, solution of caesium chloride to 200 of circulating fluid. D. Forty-five minutes after the addition of caesium chloride and an hour after the replacement of blood mixture by saline solution containing sodium bicarbonate and calcium chloride. Fig. 3. A. Trace with blood mixture. B. Effect of replacing blood mixture by saline containing chloride of calcium, chloride of barium and sodium bicarbonate. It shews also the effect of adding caesium to the circulating fluid; the caesium chloride was added at the point indicated by an arrow. C. Trace twenty minutes after adding caesium chloride and forty minutes after replacing blood mixture by saline containing barium chloride and calcium chloride.
