A light curve of the Algol-type eclipsing variable DM Persei formed from 256 visual estimates, supported by a photoelectrically determined time of minimum, indicates that the light elements of Scaltriti (1976) are reliable.  A comparison between visual and photoelectric timings of minima indicates routine visual timings are prone to large errors when long, shallow eclipses are observed.
