Timing observations of the Crab pulsar were made between 10 May 1969 to 3 July 1970. Arrival times were corrected to the barycentre of the solar system; a further correction was made for the effect of dispersion. The only jump in period occurred in September 1969, although small irregularities in the period occurred at other times. A third order polynomial fitted all the observed data to within ±0.15 pulse periods.
