before us is divided into twenty-one chapters, of which fourteen are 

 devoted to descriptions and illustrations of the details of iron and 

 steel ships. One of the remaining chapters gives a description of 

 the mode of work practised in building at the several private and 

 the royal dockyards, and another relates to operations connected 

 with armour-plating; whilst the remainder are filled up with 

 matter of a purely practical character. It would be vain to 

 attempt a perfect review of such a work as this within the space 

 allotted to us, and we can therefore do little more here than notice 

 its appearance. There are, however, one or two points of interest 

 which should not be omitted. In this book, for the fii'st time, we 

 have a detailed account of the changes made in the construction 

 of ironclads, from the 'Warrior' downwards. The arrangements 

 adopted in most of the principal private establishments with respect 

 to the various parts of iron ships are fully described ; and separate 

 accounts are given of the methods of iron shipbuilding adopted at 

 the principal yards on the Mersey, the Thames, the Clyde, and the 

 Tyne, as well as a full account of the system practised in the Eoyal 

 Dockyards in building ironclads. The style in which this work is 

 compiled seems well calculated to fulfil the author's expressed 

 desire that it should be the means of aflbrding information not only 

 to shipbuilders in general, but more especially to the officers and 

 workmen employed in the Eoyal Dockyards. By order of the 

 Board of Admiralty it will forin the principal text-book for exa- 

 mination in iron shipbuilding of candidates for promotion in the 

 dockyards. 



Although not exclusively an Engineering work, it may not be 

 inappropriate to notice here an interesting French work, entitled 

 ' Annales et Archives de ITndustrie au 19me Siecle,' * This work 

 is one of the numerous publications that have arisen out of the 

 Industrial Exhibition in Paris of last year. M. Eugene Lacroix 

 is the well-known publisher of scientific works in Paris, and at 

 the opening of the Exhibition he announced his intention of 

 publishing a report on the Paris Exhibition, independent of all Go- 

 vernment or other official authority and interference, much in the 

 same manner as ' Tomlinson's Encyclopaedia of Arts and Sciences ' 

 arose out of the first London Exhibition of 1851. The work at 

 present under notice consists of a series of volumes, purporting to 

 comprise a technology of arts, manufactures, agriculture, and min- 

 ing, compiled from essays and reports upon the different classes of 

 the Paris Exhibition of 1867, and forming a review of the present 

 state and development of the various branches of industry and 

 applied sciences and arts. The six volumes of which this publica- 

 tion consists certainly form one of the best records of the late Paris
