585. Adami, I. G. Medical contributions to the study of evolution. xviii-\-872p. Duck- 

 worth : London, 1918. — This volume of lectures and addresses is divided into three parts. The 

 first part, on adaptation and disease, contains the author's Croonian Lectures before the Royal 

 College of Physicians in 1917. These lectures contain an epitome of the author's views on 

 present evolutionary problems, and are particularly valuable for their numerous references 

 to the data of variability and mutation in bacteria and the origin of zymotic diseases. Among 

 the main points emphasized are the phenomena of "direct adaptation' 'in bacteria, numerous 

 cases being cited in support of this view, some of which are difficult to explain on any other 

 basis. A broad discussion of antitoxins, acquired immunity and related problems leads to a 

 neo-Lamarckian position, based also upon experiments on intoxication of germ cells, etc. 

 Chapter VI discusses "The physico-chemical basis of immunity and of evolution," and devel- 

 ops the conception, long since expressed by Adami, of the "biophoric molecule" as aproteid- 

 ogenous unit having "vital and heritable properties" and composed of rings or chains of amino- 

 acids, with a "nucleus" composed of a central amphoteric glycocoll group, to which are 

 attached varying orders of side chains. This conception is applied in some detail to such phe- 

 nomena as growth, enzyme action and anaphylaxis. These lectures contain vigorous attacks 

 upon the Batesonian and Weismannian positions. — In parts II and III are reprinted ar- 

 ticles and addresses published or delivered on both side of the Atlantic. Under the general 

 headings "Heredity and adaptation" and "Growth and overgrowth" are included such diverse 

 topics as variability in bacteria, inheritance of acquired conditions in man, inflammation, 

 liquid crystals, Weismannism, classification of tumors, and various aspects of cancerous 

 growths. This book serves to emphasize the reviving interest in neo-Lamarckianism on a 

 physico-chemical basis — R. R. Gates.
