KNOWLEDGE & SCIENTIFIC NEWS. 



[Dec, 1904. 



mentioned. In his introduction and chapter on practical 

 hints Mr. Stone speaks of his subject with l<nowledf;e and 

 enthusiasm, and it should be a valuable handbook to experts. 



Miscella.neous- 



Photography. — We have received for review five volumes of 

 the " Photof,'raphy " Bookshelf series, published by Messrs. 

 Iliffe and Son at is. They are intended tor practical purposes, 

 are simply written, and sufficiently illustrated. No. 10, 

 '■ Practical Retouchins," containing,' hints for after treatment 

 of the negative by Drinkwatcr Hutt, F.R.P.S., now appears as 

 a second edition. In No. 15, which deals with " Intensifica- 

 tion and Reduction," Mr. Henry W. Bennett considers the 

 methods that experience has proved to be most successful in 

 the process of stren,t;thenint,' or modifying negatives. Nos. 

 17 and iS, on " Professional Photot;raphy," by C. H. Hewitt, 

 contain chapters on such sul>jects as the Back.t,'round, Por- 

 traiture Outside the Studio, Lii^hting the Features, and Prin- 

 ciples of Composition. No. 5, " Photography in Colours," by 

 R. Child Bayley, F.R.P.S., appears as a second edition. 



Malabar and Us Folk (Natesan and Company, Madras), by 

 T. K. Gop.d Panik-Kar, B.A., describes the social customs 

 and institutions of Malabar. It contains a good deal of curious 

 and interestint; matter, set forth in a quaintly picturesque 

 language, of which the following is a typical example : " Fields 

 laden with heavy corn waving yellow in the tepid breeze, in 

 which the busy day-labourer, basking in the fierce glare of a 

 summer sun, now wipes a brow sprinkled over with drops of 

 honest toil, afford a rare and amusing spectacle. Now chant- 

 ing his wild notes, now goading and striping the lazy bullocks 

 plodding through the hardened mead, he adds to the amuse- 

 ment of the scene." 



The Optics of Photography and Photographic Lenses (Whit- 

 taker and Co. ; price, js. 5d.), by T. Traill Taylor, is published 

 as a third revised edition, with an additional chapter on 

 Anastigmatic Lenses, by P. F. Everitt. 



The London University Guide, 1905 (University Correspondence 

 College) rontains regulations for the Examinations to be held 

 in 1905-6. 



The Matriculation Directory (University Correspondence 

 College, Burlington House, Cambridge) contains the Examina- 

 tion Calendar for 1904-5, with advice as to subjects and text- 

 books and specimen papers and answers. 



The King's English and How to Write It (Jarrold and Sons), by 

 John Bygott and A. J. Lawford Jones. — A practical text-book 

 of essay and pihis writing appears in a sixth revised edition. 



Lectures Scientifiques (Rivingtons), by W. G. Hartog, B.A., 

 of University College, London, supplies a definite want and is 

 admirably arranged. Some familiarity with French and 

 German scientific terms is now essential to all students of 

 science, and more especially so since the University of London 

 has prescribed that a candidate for a scientific degree must be 

 able to read and understand French and German scientific 

 work. "Lectures Scientifiques" consists of extracts from 

 modern French scientific writers on the various branches of 

 science, with a glossary of scientific terms. 



One Thousand Objects for the Microscope (Frederick Warne 

 and Co.}, by M. C Cooke, M..A., gives practical hints for the 

 use of the microscope, with lists of objects suitable for mount- 

 ing. It is written in a pleasant, popular style, with numerous 

 illustrations, and is admirably adapted to the use of the 

 amateur microscopist. 



Private House Electric Lighting (Percival Marshall and 

 Co.), by Frederick H.Taylor, is a practical popular handbook 

 designed for the use of the amateur electrician who wishes to 

 acquaint himself with the best modern methods of the instal- 

 lation of electric light in private houses. It is useful and com- 

 prehensive. 



First Stage Magnetism and Electricity (University Tutorial 

 Press), by K. H. Juje, M.,A., D.Sc, appears as a new and 

 revised edition. It is divided into three parts — I., Electro- 

 statics ; II., Magnetism; III., Voltaic Electricity — and is 

 designed to meet the requirements of a young engineer. 



First Stage Steam (University Tutorial Press), by J. W. 

 Hayward, M.Sc.Vict., is intended to meet the requirements 

 of the Board of Education examination. It includes examples 

 of examination papers from igoi to 1904, and sugges- 

 tions for simple experiments, and is illustrated by numerous 

 useful diagrams. 



Modern Philosophers and the " Per Quem " (Elliot Stock), by 

 George Edward Tarner, is a conscientious attempt to re-affirm 

 the doctrinal tenets of Christianity, somewhat on the lines of 

 Patey's " Evidences." 



The Seven Lamps of Architecture is published by Mr. George 

 Allen in one volume at js. 6d. among his reprints of Ruskin's 

 works. This charming little edition is strongly bound, well 

 printed, and beautifully illustrated. Ruf kin lovers will gladly 

 avail themselves of this opportunity of obtaining his works at 

 so low a price. 



The Museums Journal (Vol. III., Dulau and Company), edited 

 by E. Howarth, forms a useful book of reference, and a com- 

 pendium of information about museums at home and abroad, 

 while its numerous illustrations afford interesting opportunities 

 of comparing the methods of arranging and exhibiting speci- 

 mens in l-'nglish and foreign museums. 



The Reliquary and Illustrated ArchiEologist (Bemrose and 

 Sons), Vol. X., is a delightful possession. Among many of 

 its interesting and elaborately-illustrated articles are " Notes 

 on a Roman Hydraulus." "The Evolution of the Mitre," and 

 " Medallic Portraits of Christ." 



We have also received Part VI. of Messrs. Hall and Steven's 

 "School Geometry" (Macmillan), the general principles of 

 the methods of which have already received favourable notice 

 in our columns; and " Elementary Plane Geometry " (Blackie 

 and Son), by Mr. V. M. Turnbull, which proceeds on the 

 Cambridge method of following up the experimental work of 

 measuremetit and calculation with deductive geometry. 



We have received from Mr. John Murray Professor W. H. 

 Pickering's monograph on " The Moon," and Dr. George 

 Newman's " Bacteriology and the Public Health," both of 

 which will be fully noticed in our columns next month. We 

 have also received for review " Light Energy," by Miss 

 Margaret A. Cleaves (Rebman. Limited), which will also be 

 further noticed. 



We have also received " Eton Nature Study," by M. I). Hill 

 and W. Mark Webb (Duckworth and Co.) — a book which has 

 every title to attain its desired aim of inculcating the teaching 

 of natural history and botany in schools; and " Nature Teach- 

 ing," by Francis Walts and W. G. Freeman (John Murray), 

 which aims at teaching botany to the schoolboy from an agri- 

 cultural and horticultural standpoint. It is excellent alike in 

 aim and plan. 



Messrs. Darton's Electrical Novelties. — We have received 

 Messrs. Darton's new catalogue of electrical novelties. The 

 novelties are chiefly of the kind associated with the many uses 

 to which electricity, with its great capacity for sub-division, 

 can be put in the household and the laboratory. The small 

 motors are specially adaptable to such uses ; the dynamos and 

 small gas-engines are susceptible of application to larger pur- 

 poses. Besides these, there are the many varieties of electric 

 lamps with light dry cells which can be used for bedside illu- 

 mination, for bicycles, or for railway travelling ; accumulators 

 for motor-car ignition; electric bells and their accessories; 

 house telephones; medical magnetic coils; induction coils, 

 and other devices of an analogous character.
