The fully-illustrated square paperback edition of the book on the shells that Dr. Jose Rizal collected in Dapitan during his years of exile (1892-1896). Rizal sent rare specimens of cones and cowries to Dresden, Germany through his European friends. Furthermore, Rizal cooked or burned white arc clams for the mortar mixture for his waterworks project and for his mother's lime powder for her nganga (betel nut chewing habit).
