III. " Report on the Exploration of the Caves of Borneo." By 

 A. Hart Everett. "Introductory Remarks." By John 

 Evans, D.C.L., LL.D., Treas. R.S. And "Note on the 

 Bones Collected." By G. Busk, V.P.R.S. Received 

 March 4, 1880. 



In the year 1878 the Council of the Royal Society made a grant of 

 £50 from the Donation Fund, towards the expenses of carrying on an 

 investigation of the Caves of Borneo, which it was thought possible 

 might prove to contain remains both of palseontological and anthro- 

 pological interest. A similar grant was made by the British Associa- 

 tion, and a Committee appointed ; and by the aid of private subscrip- 

 tions a sufficient sum was raised to secure the services of Mr. Hart 

 Everett, whose report upon his investigations, extending over a period 

 of nearly nine months, is now enclosed. 



A preliminary report from the Committee, together with one of 

 Mr. Everett's reports has already been submitted to the British 

 Association at its meeting in Sheffield, and has appeared in print. It 

 was then pointed out that although the examination of these caves 

 had not, as was hoped, thrown any light upon the early history of 

 man in that part of the world, yet that the evidence obtained, though 

 negative in character, was not without value, inasmuch as the true 

 nature of the Borneo cave deposits had now been carefully ascertained 

 by Mr. Everett. His final report confirms the opinion already 

 expressed. It only remains to be added that with the exception of 

 the bones mentioned in the enclosed note by Mr. Gr. Busk, F.R.S., 

 which have been placed in the Museum of the Royal College of 

 Surgeons, the whole of the objects sent to England by Mr. Everett 

 have been made over to the British Museum. Accompanying this is 

 Mr. Everett's first quarterly report, together with his map and 

 plans, so that they may if thought fit be deposited in the archives of 

 the Society, so as to be available, if necessary, for future reference.

The caves of Sarawak are situated in a limestone formation sub-
