We will obtain Faint Object Spectrograph G130H (1150--1600Angstrom) spectra of NGC 4472 (M49) and NGC 4486 (M87) todetermine the amount of intermediate temperature (~10^5 K)gas in the cooling flows and interstellar media of these early-type galaxies. Both galaxies have large amounts of hot(~10^7 K) gas, and NGC 4486 has a strong cooling flowassociated with the Virgo cluster. NGC 4472 is a relativelyisolated Virgo elliptical with a galactic cooling flow.Intermediate ionization gas traced by species such as Si IV, CIV, and N V is common in the Milky Way and QSO absorption linesystems and should be present in early-type galaxies as wellgiven their large hot gas content and apparently complex ISM.The proposed observations will have resolutions ofapproximately 200 km/sec and S/N = 15 (NGC 4472) and 35 (NGC4486). By combining the FOS observations with spectralinformation at X-ray wavelengths from the ASCA satellite, wewill be able to study the gas-phase conditions in thesegalaxies over a wide range of temperatures (~10^4-10^7 K).
