~The manufactures of Paper and Leather are briefly reported on; but 
more important are the papers on “The Construction of Iron Ships,” 
by Charles H. Palmer; and on “ The Engineering Manufactures,” by 
P. Westmacott, C.E., and J. F. Spencer. 
Valuable Appendices introduce us to Sir W. Armstrong, who 
clearly describes the construction of Wrought-iron Rifled Field-guns ; 
and to Mr. John F. Tone, C.E., who takes charge of ‘“ Railways and 
Locomotives.” 
The improvements now being carried out on the rivers Tyne and 
Tees are described by Messrs. Ure and Fowler with much pre- 
cision. 
From this notice of these volumes, it will be seen that a large 
amount of energy is expended upon the natural advantages of this im- 
portant Northern Coal-field, from which we may expect yet more 
gigantic results. Sir William Armstrong well says—“ The tendency 
of progress is to quicken progress, because every acquisition in science 
is so much vantage ground for fresh attainment. We may expect, 
therefore, to increase our speed as we struggle forward ; but, however 
high we climb in pursuit of knowledge, we shall still see lights above 
us, and the more extended our view, the more conscious we shall be of 
the immensity which lies beyond.” 
QUALITATIVE CHEMICAL ANALYSIS.* 
Tuts book has been long and favourably known to the British public. 
It is par excellence the standard work upon the subject of which it 
treats; the system of instruction is that which first met with general 
adoption in this country by the student in analysis, and the suc- 
cessive improvements in chemical methods and research have from 
time to time been duly chronicled; so that in the edition just now 
published we have at once a full and satisfactory account of all that 
is known on the subject. By the insertion of a large amount of new 
matter the dimensions of the volume have been greatly augmented, 
the present edition having been expanded to 350 pages, and in com- 
paring this with former editions it is manifest that the introduction of 
the new system of spectrum analysis has added much to the impor-
