I. Introduction. 



Nothing of a detailed character has, so far as I am aware, been 

 published on the geology of Eotuma. J. D. Dana mentions it as a 

 high island with encircling reefs in ' Corals and Coral Islands.' ^ 

 Darwin, in * The Structure and Distribution of Coral Eeefs,' ^ says 

 that it possesses a fringing-reef only, and that it has an extinct 

 volcano. 



My notes were made in the months of September to December, 

 1896, which I spent on the island ; I am indebted to Capt. Eield 

 and the officers of H.M.S. Penguin for their kindness, which 

 enabled me to visit the island. I am further greatly indebted to 

 Mr. J. E. Marr for his kindly advice and for reading through the 

 accompanying paper, and also to Mr. H. Woods, who has examined 

 the rocks which I obtained.
