Abstract
We present the results of a neutral hydrogen survey conducted with
the 100-m radiotelescope at Effelsberg of 44 northern objects in the
polar-ring galaxy atlas of Whitmore et al.(1990). These observations
were performed to complement the Green Bank observations of polar-ring
galaxies (Paper I). We detected 29 of these above our detection limit
of a few mJy. The relative content of neutral hydrogen
(![[FORMULA]](img1.gif)
) of the early-type galaxies (E, S0) in this
sample is significantly higher than for galaxies of the same
morphological types from comparison samples, i.e. for elliptical
galaxies = 0.17 ![[FORMULA]](img2.gif)
0.09 and
for S0 galaxies =0.75 0.13
which is about 6 times the mean value from the comparison samples for
the same morphological types.
Key words: galaxies: distances and redshifts; elliptical and
lenticular; ISM;
peculiar 
radio lines: galaxies
