biological science. There is no good reason why opportunity 

 for advanced work should be given in business courses or in 

 language courses and denied in the science courses. Science plays 

 a large part in the affairs of man and should be given liberal 

 treatment in any scheme of education." 



An abstract of Dr. D. T. MacDougal's address before the 

 Society of American Naturalists is given in Science, January 20, 

 191 1. As an introduction the abstract lists the recent events 

 in the field of evolution; gives brief statements of the present 

 presentation of long-recognized evolutionary theories, such as 

 isolation, geographical distribution, natural selection, and in- 

 heritance of acquired characters; and recent work showing 

 organic responses, including the plant changes secured by Mac- 

 Dougal in treating the reproductive elements of seed plants with 

 various solutions, by Gager in using radium, and by Zederbauer 

 on Capsella by climatic changes. The different mutants of 

 Oenothera secured in Amsterdam and .New York are explained 

 by the statement that "latency and recessivity of any character 

 may be more or less influenced by the conditions attendant upon 

 the hybridization." The abstract ends with a discussion of the 

 permanency of acquired characters. Not all "environic effects 

 induced in the laboratory or by transplantation are heritable, 

 although these may be carried over for two or three generations : 

 and no satisfactory basis has yet been found upon which it 

 might be predicted that any effect would be ephemeral or 

 permanent." 



Speaking of color photography in botanical work, Franics 

 Ramaley {Science, February 17) recommends that botanists 

 "make use of the new color photography especially in studies of 

 ecology and plant breeding. Many features of vegetation are 

 brought out much more clearly than by ordinary photography. 

 Thus, a moor with scattered shrubs or a lake-margin surrounded 

 with belts of different plants can be well shown. In plant- 

 breeding experiments the appearance of the different hybrids
