dc.description.abstract	BVRI polarimetry of R Lep obtained during 1984-1987 shows large changes in the normalized wavelength dependence of polarization. It is found that both the amount and position angle of polarization had components which secularly varied since their first measurements in 1966. Circumstantial evidence suggests a possible connection between the largest polarization observed in 1966 and the faintest-ever light maximum observed during 1959-60.	en
