there was an early print of prognostications by paracelsus , a tired looking copy of sir william hamiltons lectures on metaphysics and logic , a rather distressed and heavily thumbed first edition of on the origin of species by charles darwin , a leather bound and surely not original copy of philosophiae naturalis principia mathematica by sir isaac newton , a rare edition of the birth of merlin by shakespeare , a strange red book that seemed to belong to a group of individuals known as the rosicrucians , and a tattered looking journal of some kind .
