The shape and structure of radio pulses from the majority of the pulsars have been studied at frequencies of 151, 240, 408 and 610 MHz, using polarimeter receivers. Individual pulses from the stronger pulsars have been recorded photographically. The integrated pulse profiles have been obtained from on-line integration of the four Stokes parameters. Many of the results are presented graphically; the main characteristics are collected in a table. A discussion of the pulse widths and the change of polarization angle within the pulses supports the view that the integrated pulse profile represents a longitude distribution of emission, while the individual pulses represent individual beams of radiation. The changes of position angle within the profile suggest that the magnetic field has a simple configuration in the emitting region, and that it may resemble the equatorial part of a dipole field. New measurements of the rotation measures of five pulsars are presented together with a compilation of nine previous results. Some new measurements of period and position are also presented.
