Three letters written by Arthur West to Dr. James Burgess. These are:

• Letter, dated 26 February 1906, in which West writes both of his brother, Edward's death in 1905, and that he has all the 'Indian Cave papers' which he is sending to Burgess to use as he needs.
• Letter, dated 1 March 1906, in which West expresses his pleasure that the Cave notes and drawings may be published and puts them at the service of Burgess.
• Letter, dated 14 March 19906, to enclose 'a memo of our Cave experiences in India'.
