It is very hard in New York City to keep the temperature below this in summer. Although this temperature is higher than normal, the rate of respiration during the period of measurement is constant in all cases. After the measurement, the pieces were carefully taken out of the divers. They were rinsed. TABLE I I Frag. No. Rate Distal Rate FVoximal I 2 3 4 5 X .0 TABLE I.

Following this, they were dried overnight in an oven at 120° C. and were then weighed on a quartz torsion balance. RESULTS In Table I, there are five experiments made on three-day old fragments that have no primordium. Four fragments show that the distal half has a higher re- spiratory rate than the proximal portion. One fragment gives the opposite result. On the average the distal half respires more than the proximal. These results agree with the findings of Hyman (1926) and Barth (1940a)..
