According to the Third annual report of the Bureau of Ethnology, Dorsey "collected vocabularies of the Pani, Arikara, Kaddo, Kichai, and Wichita languages, to be used by the Director for comparison purposes." This series contain those notes as well as vocabulary from other Caddoan languages, notes on social structure, the names of Caddoan language tribes, and a letter from Henry Henshaw. The vocabulary that Dorsey collected was likely used in his work on Indian synonomy.
