boring at Funafuti (Ellice Is.,\ and drew attention to the remarkable 

 changes exhibited by the rocks obtained at this depth. The core 

 from this boring (a mass of material more than a ton in weight) 

 had been sent to this country by Prof. Edgeworth David, and was 

 now being submitted to careful study. The last 20 or 30 feet of 

 the boring was carried on in a rock which was of a very soft cha- 

 racter, and highly but minutely crystalline. Microscopic examination 

 shows that the rock is almost completely converted into a mass 

 of very small rhombohedra, the organic structures being nearly 

 obliterated : while a preliminary chemical examination seems to 

 indicate that magnesia has been introduced into the rock to a 

 considerable extent. The complete study, microscopical and chemical, 

 of all the stages of the change which has taken place in this rock — 

 a study which will be undertaken by Mr. C. G. Cullis — promises to 

 throw much light on processes of rock-formation of very great 

 interest to the geologist.
