C. ; Martin, P. G. Abstract This paper presents extensive observations of the properties of interstellar dust in the Large Magellanic Cloud. Extinction and polarization analysis of 12 reddened stars spread across the LMC shows that in the optical and infrared the dust characteristics are remarkably similar to the Galaxy. The wavelength dependence of the polarization and the polarization efficiency, p/E(B-V), are also comparable to galactic values. On average, the ultraviolet extinction in the LMC is also different from that in the Galaxy, having proportionately higher far-ultraviolet extinction and a weaker 2200 Å bump. The dust-to-gas ratio, E(B-V)/NH in the LMC is several times lower than the galactic value. A relationship between ultraviolet extinction properties and heavy element abundances in the Galaxy, LMC, and SMC is noted.
