— With the number for January, 1893, the Educational Review 

 opens its third volume. Professor Jenks of Cornell has a paper 

 on " Educational Values," particularly with reference to the col- 

 lege curriculum, and controverting the position taken by Pro- 

 fessor Patten in an eai-lier number. Superintendent Marble of 

 Worcester, Mass., makes some practical suggestions concerning 

 the teaching of the effective u e of English. Professor Richards 

 of Yale contrasts the old and the new methods of teaching geome- 

 try; and Principal Grant of Queen's College, Kingston, Ontario, 

 replies to Bishop Spalding's earlier argument for religious instruc- 

 tion in State schools. Important articles appear also on school 

 savings banks in England, and the effect of manual training upon 



health. The discussion on city school supervision is continued by 

 Superintendent Tarbell of Providence, and that on practice teach-

 views are contributed by Professors McLaughlin and Cameron of

— 'The Electrical Engineer will begin the new year with a series 

 of articles on the electrical and magnetic discoveries of Professor 

 Joseph Henry — the Faraday of America— by his daughter, Miss 

 Mary A. Henry of Washington, with notes by Mr. Franklin 

 Leonard Pope. Additional and pathetic interest is given this 

 series by the fact that it is practically a vindication by filial hands 

 of Henry's claims to the discovery of magneto-electricity, at a 

 tiaie when his work has been suffei-ed to fall into neglect an I 

 oblivion. At the recent Electrical Congress at Frankfort, Ger- 

 many, the proposition of the American delegates to name after 

 Henry an important new unit applying to facts that he was tbe 

 first to observe and investigate, failed of assent, and was postponed 

 until the Chicago Electrical Congress of 1893, many of the Euro- 

 pean delegates saying they had never heard of Henry.
