 Since Jaunius could not work on getting them published, Būga wrote and prepared the first volume of "Aistiški studijai" (Baltic Studies) for publication in May 1906, but after delays it was published only in May 1908.Būga also had the second volume prepared in 1906–1907, but after his own linguistic studies Būga realized that many of Jaunius' theories were incorrect and amateurish.For example, when explaining etymology of a certain word, Jaunius often searched for equivalents in the trendy Greek or Armenian languages instead of closer neighbors.
