An infrared spectrometer has been constructed with a resolution of Δλ/λ≈0·02 for observations in the wavelength range from 2·8 to 15 µ using a gallium-doped germanium bolometer (Low, 1961) as the radiation-sensitive element. Observations of the planetary nebula NGC 7027 were made with this instrument in May and June 1967 at the Catalina Observing Station of the University of Arizona. It was discovered that there was a measurable continuum flux from this object in the wavelength range from 7·5–14 µ that compared in value with the strength of stellar radiation from α Lyr (A0) at about λ = 9 µ. These observations are described in detail elsewhere (Gillett et al., 1967).
