Somewhat different responses were observed more rarely. These were char- acterized by abrupt transition from a decay curve of the usual form to a much more gradual decline towards rest level. If fascicles behaving in this manner did arrive at an elevated steady-state, rest level was probably not exceeded by more than lO^o. \Ye have no clear idea at present concerning the significance of such responses. Their rarity and the fact thai they resemble the obviously abnormal responses to high concentrations of certain chemical (see below) suggests.
