This book is a repertory of peculiar symptoms arranged in order of hierarchy. The author has studied various Materia medicas and repertories and put together 3333 keynote symptoms which act as pointers to a remedy. It would prove useful when a physician observes a PQRS symptom in a patient -- which is quite often in practice- but is unable to recall or not sure of the exact remedy. This book will help him single out the remedy and if it suits the case, can be prescribed. Also useful for students for memorising PQRS symptoms and differentiating between two similar remedies. About The Author : John Henry Clarke (1853 –1931) was an English classical homeopath. He was also, arguably, the most important anti-Semite in Great Britain. He led The Britons, an anti-Semitic organisation. Educated at the University of Edinburgh, he received his medical degree in 1877. As a physician Clarke had his own clinic in Piccadilly, London, but he also was a consultant at the London Homeopathic Hospital and did research into new homeopathic remedies.
