  As long as there is no distance indicator to the sources of gamma-ray bursts
all possible sources which are isotropically distributed should remain under
consideration. This is why the Oort cloud of comets is kept on the list. We use
the available data on the bursts' distribution of (the BATSE catalogue), and
the Catalogue of Cometary Orbits by Marsden and Williams (1992) to investigate
whether there is any observational indication for correlations between the
angular distributions of bursts and comets' aphelia, assuming that the
distribution of aphelia direction reflect, at least to some extent, true
variations in the column density of the Oort cloud. We also apply the V/V_{max}
test to both distributions. We have performed a variety of statistical tests (a
Kolmogorov-Smirnov test for the distributions in galactic latitude, a $\chi^2$
test for the spherical multiple moments, and a 2-D cross-correlation analysis),
including testing sub-samples for isolating the effect of possible
observational biases. These tests imply that it is unlikely that the two
distributions agree, but the statistical significance is not sufficient for
ruling out any connection with complete confidence. We performed Monte-Carlo
simulations which show that only when the number of bursts exceeds $\sim 800$
it is possible to rule out a correlation between the angular distributions.
Currently, it is only the combination of these tests with the large
disagreement found for the V/V_{max} parameter which makes the Oort cloud of
comets unlikely to be related to gamma-ray bursts.
