Tracing 6. Experiment 1, T.abee 3 

 The tracing is from tlie same animal as tracing 5. Following the decrease in kid- 

 ney volume from adrenalin there is a transitory slacking in urine flow. The effect 

 is comparable, though to a less extent, to the result shown in tracing 2. With the 

 increase in kidney volume following the adrenalin constriction the f^ow of urine in- 

 creases. The decrease in the excursions of the writing pen of the Hurthle mano- 

 meter are due to a partial obstruction by a clot in the connection leading to the mano- 

 meter.
