on the W edge of the PN, and one in the N part of the nebula. Both positions show a stellar continuum emission contribution from the central star. The halo emission is similar to the spectrum taken on the north edge of the PN.

### NGC 7662

NGC 7662 is a triple-shell elliptical, with a bright inner ring, a fainter outer shell, and a very faint nearly circular halo (Hyung & Aller 1997). This PN also has a large number of complex microstructures, recently examined using HST imaging by Balick et al. (1998). They suggest that there is a prolate elliptical bubble around the central star aligned perpendicular to the bright ring. The bright ring is interpreted as a torus seen at roughly 30$^\circ$ inclination.

The spectrum shown in Figure 9 was taken on the bright ring directly SE of the central star. The N end of the slit was near the central star, so some stellar continuum is seen in the spectrum, which is otherwise dominated by and lines.

### IC 351

This compact PN has a double-lobed structure with a round halo (Hua & Grundseth 1986; Aaquist & Kwok 1990; Manchado et al.1996). Feibelman, Hyung, & Aller (1996)
