Abstract
This thesis presents a study of the properties and kinematics of the neutral interstellar medium in a small sample of nearby dwarf galaxies. The selected galaxies include two dwarf irregulars, three dwarf ellipticals, and two intermediate irregular/spheroidal galaxies, most of which are at distances of rvl Mpc or less. HI synthesis images of these galaxies probe their atomic media at resolutions of 60-160 pc. Observations of CO emission in two of the dwarf ellipticals clarify the relationship between atomic and molecular gas and constrain the physical properties of molecular clouds in those galaxies. Ha images of the two dwarf ellipticals show one probable supernova remnant in NGC 185 but no other HII regions in either galaxy.
