The paper reports on the detection of 18 micron absorption features in the spectra of AFCRL809-2992, a strong infrared source found in the direction of the Cygnus X radio complex, and in an infrared object of a microwave OH 26.5 + 0.6 source. Multifilter infrared photometry of the two objects was obtained with a 2.24-m telescope at the Mauna Kea Observatory. Observations of the spectra of both objects showed pronounced features near 10 and 18 micron. A maximum absorption occurred near 9.8 micron in the AFCRL source. From the spectrophotometry of the AFCRL source a band center lying between 16 and 18 micron was indicated. These features were attributed to the Si-O-Si bending mode in silicates.
