spectra are presented for this PN, and shown in Figure 3. They were acquired with the slit centered on the core (Core), 1 east (E1), and 3 east (E3). The core position shows a contribution from stellar continuum in the $\lambda = 1 - 1.8$  region that decreases successively in the E1 and E3 positions. The unidentified feature at 2.287  is detected at the E1 position, but not the 2.199 line, similar to the findings of Geballe et al. (1991).

### NGC 6543

NGC 6543 (the “Cat’s Eye”) has a complex morphology, with a high degree of symmetry. Recent HST imaging (Harrington & Borkowski 1994) has shown more clearly the structure of rings, shock fronts, jets, and fast, low-ionization emission-line regions (FLIERS) present in this PN.

The spectrum shown in Figure 4 was taken at the position S of the central star and slightly E, where the two emission arcs cross and create a local emission maximum (see Paper I, Figure 6a). The spectra is similar to the other PN in the / - dominated class, and also show the unidentified lines at 2.199 and 2.286 .

### NGC 6572

This young PN has a bipolar morphology in the near-IR,
