Science and commerce frequently work hand in hand, and 

 materially aid each other ; but in some instances commerce 

 has been in advance of science, and this may be said of 

 the search for coral and its application for ornament, which 

 have been prosecuted for ages by the uninformed, whilst 

 learned naturalists have been debating many moot points 

 as to the growth, formation, and special localities of the 

 coral varieties. 



Our scientific men are busy dredging and exploring the
