The monograph by Prof. M. V. Ermakov in Ukranian is concerned with the elucidation of the development in the phylogenesis of the relationship between the nervous system and blood sugar level in a number of invertebrates. The author found that the nervous system begins to assume a role in the regulation of hemolymph sugar at that stage of evolution in which there appears in the nervous system a more or less differentiated sympathetic division. Such is the case in certain mollusks, lobsters, crabs, scorpions and insects. The monograph presents an interesting contribution to the problem of evolutionary physiology.
