 been bountiful beyond the deserts of the country, 

 in natural productions, but we are too apt, in the 

 love of home, to over estimate its comforts — not

 value to ourselves, but as they would be estimated

 various, or of a superior quality ; all our writers on 

 natural history have fallen into an error, we appre- 

 hend, in multiplying species unwarrantably, — 

 which will not only subject us to ridicule, but also 

 retard the advancement of true scientific knowl- 

 edge, by requiring the industry of future writers 

 to correct old and deep-rooted errors.
