Spiders: Suspended between Earth and Sky - Peter Fraser
Develop the ability to identify a 'spider' case and be able to differentiate between spider remedies.
Another episode in Fraser's series 'Transformation between the Realms'. This book examines the spider remedies, which Fraser argues need an "extremely precise and careful differentiation", if one wants to be successful in one's prescribing.
The book offers a detailed picture of the known spiders and their differentiating features.
