Abstract
The projection of computer generated fractal clouds are examined. Systematic effects depending mainly on the fractal dimension of the ISM may lead to large underestimates of the mass contained in cold gas. The constant ratio of dark mass to estimated HI mass observed in the outer galactic disks (Bosma 1981) might be attributed principally to this geometric effect.
