"Following the seven classes of smell devised by the pioneering botanist Carolus Linnaeus in his Odores medicamentorum, Watson examines the diverse roles of smell and pheromones in humans, plants, and animals. He reveals the curious ways in which trees communicate their distress, the olfactory abilities of feral children, the bond we have with our offspring, the psychosexual effects of perfume, and the link between smell and memory formation. Jacobson's Organ unlocks the door to the strange world of this mysterious sense."--BOOK JACKET.
