The main aim of this paper is to search for matter clumps in scales wi
th redshifts z similar to 1 using a new enlarged version of the QSO ca
talogue. This work confirms the evidence of the existence of anomalous
spots in the sky, where the Hubble diagram shows an extreme behaviour
, as well as the existence of a spot where there is maximum density of
absorbers. In addition to this, the work also reveals a second anomal
y of the same type, though of smaller intensity. An estimate is carrie
d out of the statistical significance of these anomalies.
