Urfan, an instrument maker from the French Pyrenees, is visited by an enigmatic bard who bears a message from a mysterious Master. This message calls on him to leave everything behind him and to embark on a journey, which will last seven years. Urfan refuses at first; however, when his family deserts him he gives himself over to his destiny and sets out on the path. During his travels he becomes a bard himself, is initiated into the ancient Celtic rites, undergoes countless adventures and comes to know true love, magic and genuine friendship. At the market of Avignon he meets Salim, an oriental dervish who then joins him on the journey. Salim embodies the wisdom of the Orient, is well acquainted with esoteric knowledge, is a Tea Ceremony Master and becomes a loyal friend. An engraved symbol hidden inside an antique pocket watch leads the companions to a secret society and into the patronage of a powerful and influential member of the lodge: Monsieur Jerome. At this noble mansion, Urfan and Salim encounter Anna, a former nun who now tends to the garden. She developed the gift of clairvoyance and her dreams and visions reveal not only the Master that had called to them, but also the way to the Mystery School. This item is printed on demand.

FIRST PRINTINGS. 16 offprints. We are pleased to offer a collection of 16 offprints by Gerhard Fankhauser. Fankhauser (1901-1981) was a professor of biology at Princeton University and an expert on embryology and cell biology. Born in Switzerland, he received his Ph.D. at the University of Berne and came to America in 1929 as a Rockefeller research fellow, joining the Princeton faculty two years later. He was internationally known for his research on the development of amphibia. In experiments using hormone manipulation and cross-breeding techniques, he studied the control of chromosomes on the amphibian life cycle. His research showed that the size of a cell is directly related to the number of chromosomes it contains. Quite popular at Princeton, he was the author of well over one hundred papers and reviews. 1. "Cytological studies on egg fragments of the salamander triton. II. The history of the supernumerary sperm nuclei in normal fertilization and cleavage of fragments containint the egg nucleus." Offprint from the Journal of Experimental Zoology, Vol. 62, No. 1, May, 1932. Pp. 185-235. Original printed wrappers.
