  Two specific families of distributions in harmonic and Clifford analysis are
further studied through a spherical co-ordinates approach. In particular
actions involving spherical co-ordinates, such as the radial derivative and the
multiplication and division by the radial distance, are computed, giving rise
to two families of so--called signumdistributions, i.e. bounded linear
functionals on a space of test functions showing a singularity at the origin.
