This is a beautifully presented hardback book, published to celebrate the fortieth birthday of the School of Homeopathy in Stroud in England. With a forward by Jeremy Sherr and an overview of 27 of the provings made by the school over the past forty years, it is a treasure trove of information and insight.
The remedies include: AIDS, Antimatter (Positronium), Arizona Basaltic Lava, Altlantic herring, Buckminsterfullerene (Buckyballs), Desert Locust, European Mole, Goosegrass, Holly, House Sparrow, Indian pipe, Kauri, Finnish Labradorite, Latex (condom), Lightning, LSD, Meadowsweet, New Water (Aqua nova), Oak gall, Peregrine falcon, Red campion, Reindeer moss, Serotonin, Welsh slate, Sloth and Southern marsh orchid.

Each substance has a core synthesis derived from the prover's diaries, a short history of the substance in nature and mythology, key themes, relevant rubrics, miasms and a mappa mundi.
