 some kind which may have the power in some occult

 of education this notion is dying out in most places, 

 and that now fewer rarities and novelties are lost 

 because it is ' unlucky' to keep them in the boat. 



The naturalist's dredge does not appear to have 

 been systematically used for investigating the fauna 

 of the bottom of the sea, until it was employed by 

 Otho Frederick Miiller in the researches which

 admirable " Descriptions and History of the rarer and 

 less known Animals of Denmark and Norway." In 

 the preface to the first volume Miiller gives a quaint 

 account of his machinery and mode of working which 

 it is pleasant to read.

 dredge not very unlike that used by Ball and Forbes

 form which we find useful for some purposes still, 

 but in most cases it gives fatal facilities for ' wash- 

 ing out ' in the process of hauling in.
