Similar changes are to be observed in the diagram of the second experiment(fig. 13) ; four contacts on the left ventricle show practically no change other thanwhat may be accounted for by the alteration of standard, errors of measurement,and replacement of contacts; a conspicuous delay is seen at the two contacts on.
