Precise specific-heat measurements have been made on low-density samples of bcc sup 3 He for temperatures in the range 0.6 to 10 mK and for magnetic fields of 0,6, and 10kOe. When plotted as a function of T/T sub c, the high-field data lie on a universal curve which exhibits a peak characteristic of a lambda-type transition.
