Results are reported for measurements leading to the calculation of standard thermodynamic properties for temperatures from T = 250 K to T = 560 K for the methylpyridines (Chemical Abstracts registry numbers: 4-methylpyridine, 108-89-4; 2-methylpyridine, 109-06-8; 3-methylpyridine, 108-99-6). The st
