Below I will analyze defensible inferences underlying the interpretation of conversational implicatures and presuppositions; a nonmonotonic onsequence notion will lead from premises including pragmatic generalizations to conclusions about how those sentences are best interpreted..

Carcinogenicity of formaldehyde in rats and mice after long-term inhalation exposure.

Groups of approximately 120 male and 120 female Fischer 344 rats and C57BL/6 X C3H F1 mice were exposed by inhalation to 0, 2.0, 5.6, and 14.3 ppm of formaldehyde gas 6 hr/day, 5 days/week, for 24 months. This exposure period was followed by up to 6 months of nonexposure. Interim sacrifices were conducted at 6, 12, 18, 24, 27, and 30 months. Significant formaldehyde-induced lesions were restric...
