Anisotropic, temperature dependent magnetization measurements on single crystals of HoNi{sub 2}B{sub 2}C indicate that there is a cascade of magnetic transitions in zero and low applied magnetic fields. Comparison of the temperature dependence of the specific heat and d({chi}T)/dT data shows a remarkable agreement in the low field limit, supporting the use of d({chi}T)/dT as a method of determining the magnetic transition temperatures as a function of applied field. The magnetic transition temperatures determined by this analysis are remarkably sensitive to the applied field and highly anisotropic. Comparison to similar data for ErNi{sub 2}B{sub 2}C show that the sensitivity and anisotropy are common features. These data emphasize the importance of anisotropic measurements of field dependent properties on single crystal samples, since the application of a magnetic field to a polycrystalline sample will effectively broaden the transition temperatures.
