The passage discusses the historical development of the Etruscan civilization, noting its influence from both the Neolithic Ligurians and the Etruscans, who are believed to have originated from Asia Minor. The author, Prof. Modestov, supports this view with archaeological evidence and suggests a connection between the Etruscan language and dialects of the southern Caucasus. The review also highlights the book's rich illustrations, particularly those of Etruscan artifacts. The second part of the passage reviews Dr. C. S. Sherrington's book on the functions of the brain and spinal cord, emphasizing the nervous system's role in integrating the body's cells into a cohesive unit. Sherrington identifies the "simple reflex action" as the fundamental unit of nervous activity and explores the anatomical basis of this reflex, including the receptor, conductor, and effector components. The review details Sherrington's experiments on the selectivity of reflexes, the irreversibility of impulse direction, and the rhythmic nature of actions. The author also discusses the compounding of reflexes and the prepotency of one reflex over another. The review concludes by praising the book for its wealth of information and lucid reasoning, despite some complex language, and considers it a significant contribution to the understanding of the nervous system.The passage discusses the historical development of the Etruscan civilization, noting its influence from both the Neolithic Ligurians and the Etruscans, who are believed to have originated from Asia Minor.
