Description: . Pp. 14. Text in Swedish. Stapled in old wrappers, slightly stained and faded and with one tear. Scarce.Frithiof Holmgren became known for his ground-breaking research on colour blindness in Sweden. This is an account of colour vision tests carried out among foreign peoples by Doctor Rudberg during the Vanadis expedition according to Holmgren's method. (In Chile, Honolulu and Japan). The results showed about the same degree of colour blindness as in Holmgren's previous tests, but the participation was considered too small to be reliable except in Japan.
