Comparison of responses to M choline, Mglycinc and M trimethylamine. Approximately 5 seconds deleted from record between glycine and trimethylamine. they are not typical. Consequently, preparations responding in this manner to J\I glycine have not been used further in this investigation. Response latency was determined approximately by means of a phonograph pick-up with a fine glass stylus positioned immediately above the dactyl in the path of the drop of stimulant, as illustrated in Figure 4, where response to a drop of sea water (Fig. 4A) appears in contrast with the response of the same units to j\I L-glutamic acid (Fig. 4B). In each display initial deflection of the upper trace signals contact of the stimulus drop with the stylus, with the largest deflection when the drop leaves the stylus. The earliest mechanoreceptor activity in Figure 4A appears after 24 msc. while the earliest obvious chemoreceptor activity is seen after about 56 msc. in Figure 4B. Conduction velocities of meters/sec, for chemoreceptor and meters/sec, for mechanoreceptor axons were estimated for this preparation by measuring the rate of propagation over a 21-mm. length of the same bundle (Fig. 4C). The latencies for this preparation consequently become msc. for the earliest mechanoreceptor and 35 msc. for the earliest chemo- receptor response to glutamic acid. Chemoreceptor latencies can obviously be ASPARTIC pH S W WASH r\.
