BEVIEWS — TECHNOLOGY. 55 



ties of the various fuels, their employment in furnaces and lamps for 

 the production of light and heat, and the construction of such appa- 

 ratus, the manufacture of gas for illuminating purposes, of candles, 

 soap, matches, gunpowder and other explosives. 



A very important branch is that which treats of the manufacture 

 of pigments aud the application of colors to textile fabrics. The appli- 

 cation of chemical science to the processes of dyeing and calico print- 

 ing, has produced the most important changes during the last twenty 

 or thirty years, and much still remains to be done in this department. 

 The manufacture of the different alkalies and of those of their salts 

 which are of industrial importance, the extraction of the various 

 metals from their ores, and the preparation of the numerous useful 

 compounds formed by them, the manufacture of china, pottery and 

 glass in all their different varieties ; the processes of paper-making, 

 glass-etching and staining, of printing and engraving, of cooking, 

 baking, and preserving meats, of manufacturing sugar and starch, as 

 well as an infinity of others too numerous to mention, all come within 

 the range of this most extensive science. 



In the University of Berlin and in others in the larger towns of 

 Germany, the plan is adopted of illustrating the lectures, not merely 

 by specimens of the various manufactures and accurate sectional 

 models, but also by personal inspection of the factories themselves. 

 Every week the lecturer makes an excursion to some foundry, gas- 

 work, porcelain manufactory, brewery or other factory, which he has 

 been describing during the week, and gives to his students on the 

 spot what may be compared to the clinical lectures of the physician. 

 Such a plan has great advantages, but is only applicable in large 

 towns where manufactories abound. In Canada a Professor of Tech- 

 nology would be rather restricted in his selections. 



The importance of the subject of Technology is, at present, so obvi- 

 ous that it is to be hoped the example of Edinburgh will be speedily 

 followed by other Universities both in England and in this country. 

 One or two passages from the Lecture Avhich has suggested these 

 remarks, will serve to illustrate its style and mode of treatment of the 

 subject. After some preliminary observations, the definition of the 

 science is thus specified in certain of its relations : — 



"It is by a quite conventional limitation, that the word Art, rex"?)* (technes,) 

 denoted by the first dissyllable of Technology, is held to signify useful, utilitarian, 

 •economic, or industrial art, for the useless arte, such as legerdemain, or the art of 

 conjuring, are eminently technical, and still more so are the worse than useless arts, 

 such as cheating at cards, and other sorts of dishonest gambling. 



■^ Nor is tbe limitation less conventional which excludes the Fine Arts from the
