title: [Factors of parallelism in the sense organs].
abstract: Factors of parallel development of the gravity receptor, traced back in phylogenesis of vertebrates and invertebrates, are presented, and associations of the receptor with the nervous system and eye are considered. The parallel development is due to the similar, hereditary fixed behaviour of animals in relation to such a definite physical factor as the gravitational field of the Earth.
