has contributed greatly to the elucidation of the laws of embryo- 

 logical development and its relation to paleontological succession 

 in his numerous papers on Cephalopods. Stimulated by some 

 criticism of his nomenclature, recently made by Messrs. Buckman 

 and Bather,* he has set forth at considerable length and detail 

 his views regarding the four different lines of research which are 

 usually described by the popular terms growth, heredity, acquired 

 characteristics and the correlations of development of the indi- 

 vidual (ontogeny), with the evolution of the group to which it 

 belongs (phylogeny). He proposes to use the technical names 

 auxology or bathmology for the first, genesiology,- for heredity; 

 ctetology for the origin of acquired characters and bioplastology 

 for the correlation of ontogeny and phylogeny, and describes the 

 field of research and the special nomenclature required for each. 

 As an analysis of the precise methods of research of the advanced 

 investigators in biology this is a useful and timely contribution.

2. A Bibliography of Vertebrate Embryology, by Chas. S. 

 Minot (Memoirs Boston Society Nat. Hist., vol. iv, No. XI, 

 pp. 487-614). — This is an elaborate, thoroughly classified list of 

 3555 titles of works treating directly or indirectly upon verte- 

 brate embryology, classified primarily under 64 groups of sub- 

 jects, then by authors alphabetically arranged. 



3. A theory of Development and Heredity, by Henry B. 

 Ori:, Ph.D., 225 pp. 8vo, (Macmillan & Co.) — This is a theory of 

 evolution from the psycho-physiological point of view. The sub- 

 stance of Prof. Orr's theory is given in the following sentences : 

 "It would be difficult in the face of the facts to imagine that 

 organic development differs in nature from psychic activity, or 

 rather to speak more accurately, from the material accompani- 

 ment of psychic activity" (p. 239), and "the intelligent human 

 action and the simplest process of growth are thus alike the 

 necessary result of the stimuli which are momentarily acting, 

 and those which have acted upon the organism through its racial 

 and individual existence " (p. 242). w. 



4. Bulletin from the Laboratories of Natural History of the 

 State University of Iowa. Vol. II, No. 4, pp. 295-415, Plates 

 I— XII, Nov., 1893. Iowa City, Iowa. — This number contains ten 

 separate papers, the majority of which are micro-anatomical 

 studies of animals and plants. Mr. Shimek in the fifth paper 

 gives an account of a Botanical Expedition to Nicaragua in 

 which the country traversed and its climatic conditions are de- 

 scribed. The number and kinds of plants gathered is given but 

 without generic or specific definition. Prof. McBride described 

 (p. 391) a new Cycad, Bennettites Dacotensis from supposed 

 Mesozoic rocks, near Minnekahta, S. Dak., the description having 

 originally appeared in Am. Geologist, Oct., 1893. w.

 Lydekker, pp. 411 (Horace Cox, London, 1893). — The work is a
