mineralogist \Yeiss, thus folloiving the example of Hartmann, m his 

 System of Mineralogy. The method is good, in so far as the general 

 chemistry of minerals is concerned, hut the want of physical character- 

 istics of classes, orders, families, and genera, renders the work less imme- 

 diately useful than it would otherwise be to the young mineralogist, 

 who, owing to these omissions, is left to the uncertain mode of discovering 

 the place of the species in the system by an appeal to the index. In the 

 next edition of Mr Nicol's Manual, we would recommend him to supply 

 this deficiency, which we know he is fully competent to do.
