Gaussian analysis of 21-cm profiles of high-velocity clouds reveals the existence of two well-defined components: one with mean velocity widths of about 7 km/s and the other with mean widths of about 23 km/s. These components are correlated with the morphological structure described by Giovanelli et al. (1973): small velocity-width components correlate with small bright condensations in the high-velocity complexes, while larger width components correlate with more extended faint regions. Because both components appear associated with distinct clouds, however, they are interpreted as representing two phases of a three phase galactic gas. Analogies with UV interstellar absorption and 21-cm line absorption observations are discussed.
