This paper analyzes results of measurements of the period derivative, the period coordinates, and the magnitude of noise fluctuations during the arrival of 16 pulsars observed between 1978 and 1986. Particular attention is given to measurements of the forms of abrupt changes ('jumps') in the period characteristics of two pulsars: PSR 0355 + 54 and 0823 + 26. For the PSR 0355 + 54, a decrease in the period derivative before the first jump was found; after the jump, an unusual form of the rotation-velocity-change function was observed. A small jump was detected in the period of PSR 0823 + 26, followed by a discontinuous change in the rotational velocity. For eight of the 16 pulsars studied, a comparison of measurements with literature data covering earlier periods revealed significant changes in period derivatives.
