Ko tana pukapuka 1919, Geometrische Kristallographie des Diskontinuums, i whai waahi nui ki te whakapai ake i te ariā roopu mokowhiti. I roto i tenei pukapuka, i whakaatuhia e Niggli ahakoa ko nga tikanga whakaata X-ray kaore i te whakatau i te roopu mokowhiti e pa ana ki te karaihe, ka whakaatuhia e raatau he iti o nga roopu mokowhiti ka taea e ia. I whakamahia e Niggli nga tikanga morphological hei whakaatu i te hanganga o roto, a, i roto i tana 1928 Kristallographische und Strukturtheoretische Grundbegriffe, i tangohia e ia te mea ko te tukanga whakamuri, ko te mahi ki te whakapumautia te hononga i waenga i nga waahi mokowhiti me te morphology tioata o waho. Ko te whāinga nui o tōna oranga, ko te whakauru i te āpure katoa o ngā pūtaiao o te Ao.  Patai: I whiwhi a Niggli i tana tohu tohungatanga i hea?
