What has the author C G Conradi written?

C G Conradi was a Norwegian linguist who lived from 1848 to 1908. While he may have written works related to his linguistic studies during his lifetime, I need more specific criteria or context to accurately name specific writings or books, such as titles or subjects of interest related to C G Conradi. Since my knowledge cutoff is January 2021, newer publications related to him post January 2021 are currently beyond my scope of understanding.
