The authors present results of a continuing program of photoelectric magnetic field measurements of helium-strong stars. Nine of the 11 helium-strong stars so far observed for circular polarization in the wings of Hβ have shown evidence of large, ordered magnetic fields. The discovery of two new magnetic helium-strong stars and observations of seven other members of the class are reported. They also discuss new measurements of the helium-weak star HD 175362. Magnetic curves have been obtained using the He I λ5876 line for four stars. After revising the measured v sin i values of three of the helium-strong stars, it is demonstrated that the v sin i distribution for the helium-strong stars is similar to the distribution for normal early B stars.
