Richard Evan Schultes and Albert Hofman. Foreword by Heinrich Kluver. 
 
Charles C Thomas: 1973. First edition. Hardcover in a jacket. Octavo. Minor folds, fading, and chipping across the top of the jacket. Some soiling on the jacket, a little more along its spine. Bumping all along the top and bottom of the boards, including the corners. Some foxing on the top and fore edges of the text block. 265 pages. Book is very good, jacket is good. Warmly inscribed from Dick Schultes: "To old friends Renee & Jimmie with all my best gratitude - friends who, in finding us our house, have given us years of happiness." 
 
One of the first of its kind as a precise overview of these substances. Includes both chemical breakdowns of psychedelic plants studied in Western laboratories and until-then-ignored notes on hallucinogenic plants used in indigenous societies. 
 
"Turning from the world of hallucinogens botanically viewed to the world of hallucinogens chemically viewed, I share Albert Hofmann's regret (expressed in 1967, when he could not attend a meeting in this country) that psychoactive drugs. while spanning space and time psychically, cannot yet do so physically by transporting us on a 'flying carpet' from one region of the globe to another."
