1. Introduction

In a preliminary analysis of the dynamics of 77 theoretical streams associated with short-period comets moving in the orbits distant from that of the Earth and having an orbital period shorter than 10 years, we found that the particles of theoretical streams of 21 comets came within AU of the Earth's orbit and the particles of 14 of these comets could be identified with observed meteors. Three of these comets, D/1895 Q1 (Swift), 14P/Wolf, and 43P/Wolf-Harrington, are the best candidates to be the parent bodies of observable meteor showers. In the case of comet 14P/Wolf, we found (Neslusan 1999) that the modelled meteor stream corresponds to a part of the observed, complicated meteor shower, Capricornids.

The modelling of the stream of 14P/Wolf and its identification with observed meteors show that the observable structure of the stream is wider and one part coincides with the modelled and identified stream associated with comet D/1892 T1 (Barnard 3). This could be expected because the orbit of D/1892 T1 was very similar to that of 14P/Wolf before 1922. In this study, we give a more detail analysis of the observable structure of the comet 14P/Wolf stream as well as an analysis of the stream associated with comet D/1892 T1 overlapping that of 14P/Wolf.
