In thisay a given eye can be measured many times without disturbing it 52 by jars or other forms of mechanical stimulation except when it isnecessary to change the sohition in the container. Since the unit that most concerns us in this i)aper is tlie timerequired by the pupil to dilate to a maximum it becomes necessaryto explain a few points in this connection. (1) In some eyes tli<long axis is the first to reach a maximum length; at other times itis the short axis. (2) The axis first to reach a maximum lengthusually shortens while the other axis is in the process of elongating:.It is only occasionally that both axes reach their maximum lengthsimultaneously, or that th
