A generalization of the coordinate-free approach to limits of Paiva et al. to include non-vacuum space-times is made. Geroch's work on limits of space-times is also extended. The same argument also justifies part of the procedure for classification of a given spacetime using Cartan scalars.LaTeX, 21 pagesGeneral Relativity and Quantum CosmologyAstrophysicstext
