The velocity dispersion of the old LPVs (33 km/s) indicates that they belong to a spheroid population. A rotational analysis of various disk populations of the LMC (H I, CO clouds, PN, CH stars, clusters, and LPVs) indicates that the transverse velocity of the LMC is about 200 km/s in the direction of the Magellanic Stream, that the dynamics of the LMC is dominated by a single rotating disk, and that all populations in the bar have solid-body rotation. The distribution of outer old LPV velocities implies a mass of the LMC of approximately equal to or less than 6.2 + or - 1.5 x 10 to the 9th solar masses. The old LPV population has a mass of 1.1 x 10 to the 8th solar masses, or about 2 percent of the LMC's total mass.
