In fact those scientific publications which, are devoted to 

 the furtherance of Natural History, contain a large proportion 

 of papers such as would result from either of the above 

 methods. 



The pleasure which is invariably experienced in the study 

 of natural objects would be considerably increased by such 

 methodical working. When a man is able to add a fresh 

 species to his list, it is done with no small amount of satis- 

 faction ; and the monotony of a dull voyage cannot but be 

 considerably relieved by such an occurence. Moreover in 

 comparing the list of his own captures in any particular class 

 of animals, with the published lists of species known to exist, 

 he will, not fail to find in it many deficiences. This will lead 

 him to search more carefully, in order to obtain the species 

 that are wanting ; and he will probably succeed in obtaining 

 many which otherwise he would never have met with. In all 

 probability a few will still be lacking, and he will be led to 

 take a deeper interest in studying the distribution of species 

 the limits of their range, and the conditions essential to their 

 existence. No more appropriate or more interesting subject 

 of research can be taken up by the Mercantile Marine.
