Los Restos Indígenas de Pichilemu (The Indigenous Remains of Pichilemu) was a 1908 book published by Chilean historian José Toribio Medina. Medina presents a report of his examination to indigenous rests found in a Pichilemu grotto (currently named Virgin's Grotto—Spanish: Gruta de la Virgen) by Agustín Ross and Evaristo Merino in 1908. The book contains two sheets, that show some tools that Promoucaes indigenous used. * One of Medina's sheet, published originally in the book.
