The preliminary results of time-resolved spectroscopy of the He White Dwarf system AM CVn are presented. Spectral variations at different photometric periods have been searched for. These are found at different time scales although this does not particularly favor any of the searched periods.

Results are reported from a CO (J = 2-1) survey of nine type I nebulae using the 12-m NRAO antenna at KPNO; the data are presented in tables, graphs, and contour maps and briefly characterized. Three of the nebulae are found to have significant CO emission, with evidence of (1) dissociated molecular envelopes, (2) complete ionization of the gas by
