A rare work on dowsing rods, or "baguettes" (i.e., the same word used for the popular, archetypal French bread), written by the French Roman catholic priest Pierre Le Brun (or Lebrun) (1661-1729). Le Brun was an early sceptic, denouncing dowsing, or divining, in this work. Although not stated, this is a second (title) edition (first: 1693). The elegant binding shows skilled craftmanship. On the front pastedown a trimmed mineralogical bookplate of the French mineralogist and professor at the École des Mines, Claude Jean Guy Guillemin (1923-1994), who was a co-founder of the International Mineralogical Association. Internally a very good, clean copy. Rare in any state. Neither in Thorndyke, nor in Brunet.
