The purpose of a review of a scientific monograph is twofold: 1) to give a brief summary of the contents, organization, methodology, and main conclusions of the work; and 2) to comment critically on its contribution in the light of the author's aims and techniques. Unfortunately, the recent review by Stig Rydén (1958, American Antiquity, Vol. 24, No. 1, pp. 88-9) of Heyerdahl and Skjölsvold, Archaeological Evidence of Pre-Spanish Visits to the Galápagos Islands does not serve either of these purposes.
