The results of a kinematic study of the narrow- and broad-line regions in Mrk 359 are presented. The emission-line profiles between 4600 and 7500 A are used to derive the physical characteristics of the line-emitting gas. Many aspects of the emission-line profiles of Mrk 359 make this object an exceptional Seyfert galaxy: extremely small widths of both the forbidden lines and the broad component of the permitted lines, absence of profile substructure, large blueward asymmetry of the high-ionization forbidden lines despite the apparent absence of reddening in the narrow-line region. Various scenarios are proposed to explain these results. 65 refs.
