have for a long time been favoured. The most attractive feature of the work 

 is its very handsome and numerous plates, which are all executed in photo- 

 lithography by W. Griggs, of Peckham. Many of the plates are printed in a 

 number of colours. It would be impossible to describe the contents of each 

 number. We will take No. 12, which was published in June, 1887. It con- 

 tains a portrait of her Majesty the Queen-Empress; II. H. the Rlaharaja of 

 Jeypore ; H.H. the Maharaja of Ulwur ; Plan of the Indian Courts of the 

 Colonial and Indian Exhibition ; the Jeypore Pavilion and Screen ; Details of 

 Screens ; and many others. The letterpress accompanying each part is des- 

 criptive of the Arts and Industries of India. 



Natural Philosophy for Beginners : Mechanics, Hydro- 

 statics, and Pneumatics. By William Nicolls, B.A. Third edition ; pp. 122. 

 (Dublin : E. Ponsonby. 1887.) Price 2s. 



We are glad to see that this useful little work has reached its third edi- 

 tion. Although written in the first place for intermediate schools, it will be 

 found of much value for all students who are desirous of mastering the 

 elementary laws of matter and motion. The first part treats of the fundamen- 

 tal properties of solids, liquids, and gases, including an account of the metric 

 system of weights and measures, and descriptions of the various mechanical 

 powers. The second part forms a first step to the study of statics, pinetics, 

 and hydrostatics, Newton's laws of motion being, of course, taken as the fun- 

 damental basis on which the dynamical properties of matter depend. The 

 introduction of the conception of Veetors in treating pinematical propositions 

 is much to be commended, as giving the student an early notion of modern 

 dynamical views. Each chapter is illustrated by numerous examples and well- 

 selected questions, a set of miscellaneous examples being appended at the end 

 of the work. It is surprising what a large amount of information Mr. Nicolls 

 has condensed into this little book. Moreover, this has not been done at the 

 expense of clearness, for tlie explanations are remarkably lucid and easy of 

 comprehension. 



The Divided Irish. By the Hon. Albert S. G. Canning, 



author of " Revolting Ireland, 1798 and 1803," "Thoughts on Shakespere's 

 Historical Plays," etc. Crown 8vo, pp. 86. (Newry, Ireland ; ]. Warnock 

 and Co. 1888.) Price is. 



In the little book before us Mr. Canning has collected his facts from a 

 great variety of sources, and assures us that he has endeavoured to treat 

 modern Irish history with thorough impartiality. It will donbtless be read 

 with much interest at the present time. 



La Photographie Moderne : Pratique et Applications. Par 



Albert Londe. Royal 8vo, pp. 312. (Paris: G. Masson, editeur, Libraire de 

 I'Academie de Medecine, 120 Boulevard St. Germain. 1888.) 



Of the many useful treatises on photography that have come before us, we 

 think that we may fairly award to the present work the position of the first. 

 Not only is it a handsome volume, well printed, and well illustrated, but it 

 carries down the practice of the photographic art to its latest developments, 

 its application to astronomy, or, rather the charting of the stars and the repro- 

 duction of the lunar features, which are well illustrated and explained ; instan- 

 taneous photography, as a means of investigating the tiight of birds and the 

 actual movement of animals ; the use of the camera in the field, both for 

 peaceful and warlike purposes, are well brought out. We have no hesitation 

 in recommending this work to our readers as one of the best, if not the best, 

 of its kind.
