Science Progpess in the Twentietii Century. A Quarterly 

 Journal of Scientific Thought. N. H. Alcock and W. G. 

 Freeman, Editors. (John Murray, Albemarle St. London 

 5/- quarterly. No. 1. July 1906 p. 1—176. No. 2. October 1906 

 p. 177—364.) 



The jotirnal is devoted to comprehensive summaries of recent 

 work and to general discussions of topics of interest to workers in 

 all branches of science. The papers are as far as possible non- 

 technical although not "populär". Thus, the chemist, to take an 

 example, describes for the botanist recent advances in chemistry 

 whilst the botanist does the same Service for the chemist. Special 

 attention is paid to bibliograph}^ to render the papers of greater use 

 to students and others desirous of pursuing the subject further.
