This book is interesting but their are many Constitutinal types not covered that are extremely interesting such as Plumbum, Zinc, The Magnesiums. Conium and Cuprum metallicum and the Ferrums to note a few.
About the remedy Aurum. Bailey does not talk about the Females of Aurum and he does not seem to understand that Aurum also has GOOD QUALITIES. The Aurum is the person who has a HEART OF GOLD. She is also the person who is WORTH HER WAIT IN GOLD.
Dont worry Philip Bailey. Even the best Homeopaths dont know it all.
