 note = {A lower limit to the distance of a high velocity HI cloud (HVC) can be estimated from 21 cm radio observations taking into account the stability of the cloud against the tidal disruption force produced by the gravitational field of the Milky Way (Watanabe, 1981). This method is applied to the 21 cm observations published by Meng and Kraus (1969) and Hulsbosch (1975). Since obtained lower limits to the galactocentric distances of apparently circular HVC's observed by these authors are between 20 and 100 kpc, these HVC's will be the satellites of the Milky Way. Using these estimated distances of HVC's, kinematics of HVC's are discussed. The kinematics of the HVC's which have small galactocentric distances of around 30 kpc can be explained in terms of elliptical orbits with eccentricities of larger than 0.9 if we assume a galactic mass of 1.4 X 10^11Mʘ. However, the kinematics of several HVC's cannot be explained under the assumption of this galactic mass because of large perigalacticon distances and large galactocentric velocities. A possibility of larger galactic mass of, at least, 6 X 10^11Mʘ is suggested.},
