[N. S. Vol. XLIV. No. 1126 



a dean of one of the institutions : The mem- 

 bers of the United Medical Committee, in 

 charge of the medical school of the University 

 of Pennsylvania and the Jefferson Medical 

 College, of Philadelphia, have agreed that it is 

 advisable to postpone the consummation of 

 the union agreed on by the plan adopted by 

 the trustees of the two institutions, in order 

 that further opportunity may be afforded for 

 considering a number of important matters 

 relative to the mode of administration of the 

 new school, and have, therefore, determined 

 that each of the schools shall conduct, sepa- 

 rately from and independently of the other and 

 of the United Medical Committee, the work of 

 its college term for 1916-17. 



Professor "Walter S. Hunter, of the Uni- 

 versity of Texas, has been appointed professor 

 of psychology in the University of Kansas, to 

 fill the vacancy caused by the removal of Pro- 

 fessor Eobert M. Ogden to Cornell University. 



At Indiana University, Professor W. N. 

 Logan, director of the school of general science 

 in the Mississippi Agricultural and Mechanical 

 College, has been appointed associate pro- 

 fessor of economic geology; and Mr. C. A. 

 Malott has been appointed instructor in 

 physiography and geology. Dr. J. J. Galloway, 

 instructor in paleontology, has accepted a po- 

 sition as curator of paleontology at Columbia 

 University. 



Harrison K. Hunt, Ph.D. (Harvard, '16), 

 has been appointed instructor in zoology in 

 West Virginia University. He takes the place 

 of J. Theron Ulick, who will sail for China in 

 the autumn to accept a teaching position there. 



At the Michigan Agricultural College, Mr. 

 G. E. Johnstone has resigned his instructor- 

 ship in botany which he has held for three 

 years, in order to prosecute his studies 

 further. The vacancy has been filled by the 

 appointment of Mr. H. C. Young, who was at 

 the Missouri Botanical Garden last year. 



We learn from Nature that the Manchester 

 City Council (governing body of the Man- 

 chester School of Technology) has established 

 a new subdepartment of the school of post- 

 graduate study and research in coal-tar prod- 



ucts and dyestufis, and has appointed Pro- 

 fessor A. G. Green, F.R.S., to take charge of 

 it. Professor Green recently resigned the chair 

 of tinctorial chemistry at Leeds University in 

 order to direct the research department of a 

 firm of dyestuff manufacturers. His sub- 

 department will be under the general direction 

 of Professor Kneeht, who is head of the de- 

 partment of applied chemistry, and is expert 

 in the use of dyestuffs, as Professor Green is 

 expert in their manufacture. 



It is announced in the London Times that 

 Dr. A. E. Evans, lecturer in chemistry in 

 University College, Reading, has been placed 

 in charge of a new department of the Hud- 

 dersfield Technical College for special study 

 and research in coal-tar color chemistry. It 

 is expected that a number of scholarships will 

 be tenable in the department. The directors 

 of British Dyes (Limited) are supporting the 

 scheme, and are prepared to contribute sub- 

 stantially towards its institution. At Leeds 

 University there is already a department of 

 color chemistry and dyeing, the endowment 

 of which was provided by the Clothworkers' 

 Company. 



DISCUSSION AND CORRESPONDENCE 



AN ENGINEER'S IDEA OF ENERGY 



To the Editor of Science : In a recent num- 

 ber of Science 1 Professor Kent takes excep- 

 tion to some criticisms of mine on the " cur- 

 rent definition of energy." In his opening 

 sentences he states that in seeking " some 

 language in which to convey to students an 

 engineer's idea of energy " he wrote : " Energy, 

 or stored work, is the capacity for performing 

 work" and proceeded to extend and illustrate 

 his definition. 



Now if he had only " stuck to his idea " and 

 prefaced his statement in his book with the 

 words he here uses in his above explanation, 

 so that his statement would have read : " An 

 engineer's idea of energy, or stored work, is 

 the capacity for performing work, etc.," no one 

 could have taken exception to his statement. 

 It would have been true and, except by other 

 engineers, not open to dispute. But when he
