Little are they aware how fantastic arc the tricks which 

 thiy play, " like an^ry apes hefore hif^h heaven," in the 

 eyes of all those, whether naturalists or sportsmen, who do 

 not confound conceit with knowledge, or wit with iinpcrtiueut 

 vulgarity. 



I ^hall now jiroceed to a fi-w ohscrvations with regard to the 

 figure No. 1, in the last wood-cut, on page I'J, whieh represeuts 

 the interior of the mouth, opened to the utmost, of the Common 

 Trout of (ireut Britain and the European continent {Salmo 

 Fiirio) ; whieh is selected hy Mr. Varrel as "showing" — to 

 horrow his own words — " the most complete series of teeth 

 among the Salmonidfe ; and the value of the arrangement, as 

 instruments for seizure and prehension, arising from the inter- 

 position of the dillcrcnt rows, the four lines of teeth on the 

 lower surface alternating, when the mouth is closed, with the 

 five rows on the u|)pcr surface, those on the vomer shutting in 

 between the two rows on the tongue," &c. 



In this cut, letter a represents the situation of the row of 

 teeth that is fixed on the central bone of the roof of the mouth, 

 called the vomer, from some fancied resemblance to the share 

 of a plough, for which the word used is the Latin term ; 

 nil, refer to the teeth on the right and left palatine bones; 

 c, to the row of hooked teetli on each side of the tongue ; 

 n D. to the row of teeth outside the |)alatinc bones, on the 

 upper jaw, which arc those of the superior maxillary bones;
