Observations of the 21-cm neutral hydrogen absorption spectra of the strong radio sources Vir A, Cyg A, and Cas A have been taken with the Mark IA radio telescope. Cloud and intercloud gas can be identified in these absorption spectra and in adjacent emission spectra. The observed values of the spin temperature of the hot intercloud gas are in the range from 600 to 8000 K; the corresponding kinetic temperature range extends from 770 to just under 10,000 K. There is evidence for an increase in the kinetic temperature with height above the galactic plane. Some implications of these first direct observations of the temperature of the neutral intercloud gas are discussed.
