This book deals with nervous manifestations ascribed to loss of blood. The following seven posthemorrhagic symptoms and syndromes are treated, each with personal case records and bibliography: hemiplegia; paraplegia; convulsions; larval pyramidal syndromes; psychic phenomena; coma with hypertonia; ocular and cranial nerve phenomena. The results of experiments on many varieties of animals are related. Finally, there is a chapter on pathogenesis and therapeutic deductions. It is emphasized that certain local preexisting lesions, especially of the brain and liver, predispose to the occurrence of nervous phenomena which rarely occur if the organs are normal. The effect of transfusion shows that these phenomena are to a great extent reversible.
