Mr. Jukes remarks, and I believe, most correctly, that “if the term ‘jura kalk’ is applied lithologically to these tertiary rocks, it is to a certain extent applicable, as they have a concretionary and oölitic structure. If, however, it is meant to have a chronological meaning, it is either incorrectly applied, or the formation is incorrectly extended on the map to the neighborhood of Kupang.”
