1. When cockroach salivary glands are exposed to bathing solutions without added calcium, reintroduction of calcium causes the acinar cells to hyperpolarize. The effect ('readmission response') may be very prolonged if the conditioning solution contains 5 mM‐cobalt. 2. Evidence is presented against the possibility that the readmission response is mediated by transmitter released from the salivary nerves. 3. The readmission response is shown to reflect an increase in potassium conductance.
