about one point out of fourteen for admission. 

 My present data, derived from official sources, 

 here follow, but they are, for sundry reasons, 

 incomplete. I -wish to request that any reader 

 of this note who is connected with a univer- 

 sity, college or technical school, will make 

 sure whether his institution is correctly repre- 

 sented in the lists below, and if not I shall be 

 very grateful if he will communicate to me 

 the suitable correction. I shall later publish 

 a supplementary list, and finally a complete 

 one in connection with other related data. 



The following institutions accept the Col- 

 lege Entrance Examination Board's examina- 

 tions in botany, and state the fact in their 

 official publications: Bryn Mawr, California, 

 Cincinnati, Columbia, Cornell, Dartmouth, 

 Harvard (although it can count for only a 

 half year), Illinois, Leland Stanford, Maine, 

 Massachusetts Institute of Technology, Massa- 

 chusetts Agricultural College, Mount Holyoke, 

 Nebraska, Northwestern, Ohio, Pennsylvania, 

 Rochester, Simmons, Smith, Syracuse, Wash- 

 ington (St. Louis), Wellesley, Wells, Ver- 

 mont, Woman's College of Baltimore, Tale 

 Scientific School. 



The following institutions, I am assured, 

 accept the board's examinations, although at 

 last accounts no mention of the fact had been 

 made in their official publications: Chicago, 

 Haverford, Kansas, Minnesota, Missouri, 

 North Carolina, Oberlin, Wabash, Williams.

SCIENTIFIC BOOKS 

 Radiation, Light and Illumination. A Series 

 of Engineering Lectures Delivered at Union 

 College. By Charles Proteus Steinmetz, 

 A.M., Ph.D. Compiled and edited by 

 Joseph Le Roy Hayden. Pp. xii + 305. 

 New York, McGraw-HiU Book Company. 

 1909. 



This latest book from the pen of Dr. Stein- 

 metz constitutes to some extent a departure 

 from his previous writings. In it an attempt, 

 perhaps the first definite attempt, has been 

 made to bring together not only the principal 

 physical facts, but also many of the more im- 

 portant physiological facts which pertain to 

 the effects of luminous and attendant radia- 

 tion. The view-point throughout is that of 

 the engineer. The book is the outcome of a 

 series of lectures to engineering students. It 

 is intended in the author's words in the pref- 

 ace " not merely as a test -book of illuminating 

 engineering, nor as a text-book on the physics 

 of light and radiation, but rather as an exposi- 

 tion, to some extent, from the engineering 

 point of view, of that knowledge of light and 

 radiation which every educated man should 

 possess, the engineer as well as the physician 

 or the user of light."
