Scientific paper

Evidence is presented in support of the existence of a universal law relating the local light to the local mass at each point in a galaxy. The form of the law is given for the inner parts of the disk of a spiral galaxy. The implication is that when the photometric parameters of a disk are established, the distribution of mass in the dark halo is automatically established as well. A method of extending these calculations to SOs and ellipticals is also presented; the method, however, relies on more data becoming available.
