Fig. 8.1. The rate of secretion of the submaxillary gland of a cat recorded 

 with a capacitance flow meter. 

 Ordinate rate of flow in ml. per minute. Time marked seconds. In series A, the ipsilateral 

 cervical sympathetic trunk was stimulated maximally at the frequencies indicated. In series B, 

 the chorda tympani was stimulated (Burgen, unpublished). 



produced by the submaxillary gland varies very little (Wechsler, 

 unpublished). This is surprising since the neonatal gland has only 

 a few poorly developed acini, although large dilated tubules are 

 present. The rate of water secretion by this gland seems to proceed
