On this trip I was accompanied by Dr.Ales Hrdlicka.

I revisited the Tarahumares and Huichols in order to supplement the material in hand and to settle doubtful points that had come up in working out my notes.

Sixty melodies from these tribes were recorded on the graphophone.
Thus from 1890 to 1898 I spent fully five years in field researches among the natives of northwestern Mexico.

The material was collected with a view to shedding light upon the relations between the ancient culture of the valley of Mexico and the Pueblo Indians in the southwest of the United States; to give an insight into the ethnical status of the Mexican Indians now and at the time of the conquest, and to illuminate certain phases in the development of the human race.
