Abstract
The long-term variability of PKS 0735+178 in B band is shown with some new data presented and discussed by means of Jurkevich's method. The results show with good possibility the presence of a period of 14.2 ye ars. The period of 4.89 years found by Webb et al. (1988) and Smith et al. (1987) might be confirmed with more observations, and their perio d of 1.2 years can be ruled out.
