The first volume of this stately work deals with various venomous animal species, including protozoa, insects and fishes, and the second with the venomous batrachians, lizards and snakes. During the last thirty years Césaire and Marie Phisalix have published more than 200 articles dealing with venomous animals. Césaire Phisalix was one of the discoverers of antiserum for snake venom. After his unfortunate and premature death in 1906, the investigations were continued by Mme. Phisalix, who in 1916 received the Bréant prize from the Academy of Sciences. The present work is a great triumph for this intrepid woman of science. Profusely and artistically illustrated and provided with full bibliographies and indexes, it is the most complete work so far published on venomous animals and venom intoxication, and will be a landmark of continuous value to zoologists, physiologists and physicians.
