The emergence of an `assemblage' of `integrant points' according to Bravais. The `rows' OAA'A''..., ABB'B''..., with `parameter' OA first constitute a plane `lattice'. A stacking of such `lattices' following ODD'D''... produces the `assemblage' which models the crystal (Bravais, 1848BB3).  [article HTML]
