Ebook: Essay on the grammar of the Yukaghir language

Jochelson, Waldemar. 1905. Essay on the grammar of the Yukaghir language. Annals of the New York Academy of Sciences 5:2. 97-151.
I took up the study of the two dialects of Yukaghir language in 1895-97 during my participation in the Yakut Expedition, fitted out by the Russian Imperial Geographical Society [...] I mastered the Yukaghir language sufficiently to obtain full command of their grammatical forms, and not only to take accurate record of the texts, but also to converse freely in it.
