Abstract: VLA observations are used to measure the H I spectrum of the symbiotic nova HM Sge. It is found that the H I column density to HM Sge is 4 x 10 to the 20th/sq cm and that the upper limit to the mass of circumstellar H I is 0.008 D-squared solar mass, with D equal to the distance to HM Sge in kparsecs. In addition, the spectrum of the quasar O V + 168 is used to show that the total Galactic H I column density in the direction of HM Sge is 9.5 x 10 to the 20th/sq cm. The implications of these results on the interpretation of other observations of HM Sge are discussed.
