The effect of massive galactic halos on the flow of supernova-heated hot gas in early-type galaxies is substantial when the flows are computed for times comparable to the Hubble time. Two elliptical galaxies with masses of 3.1 and 8.3 trillion solar masses having dark massive halos which contain 90 percent of the total mass are considered. Interstellar gas ejected at early times, when the stellar mass-loss rate was several times its present value, produces a wind with a cooling inflow at the core. After several billion years, this gas moves into the dark halo, slows, and restricts the outflow of the wind near the galactic center. Eventually, after about 10 billion yr, the sense of the entire flow reverses, flowing slowly inward in approximate hydrostatic equilibrium. The X-ray luminosities of the hot gas are in excellent agreement with recently reported Einstein observations of early-type galaxies.
