1 823 J the natural Distribution of Insects and Fungi 337 



To conclude : If an arrangement be natural, it will stand any- 

 test ; and to support the truth of this proposition, I shall now 

 arrange Annulose Animals in the same way that M. Fries has 

 distributed his Fungi, when it will readily be seen as virtually 

 nothing else than the arrangement T oiiered to the public in the 

 Horce EntomologiccB, Thus it is only necessary that instead of 

 subjecting Nature to arbitrary rules of our own invention, we 

 should humbly receive her laws as she clearly proclaims them ; 

 when she will indeed appear, as M. Fries has found her to be, 

 " ubique varia, semper tamen eadem." 



Classification of Annulosa on the same "Principles as those 

 adopted hy M. Fries in his natural Distribution of Fungi, 



Annulose Animals, which are not hermaphrodite : or the 

 An NU LOS A of Scaliger may all be divided into two groups 



founded on their larva or foetus state, viz. 

 .1. Apterous Insects, having either no metamorphosis in the 

 usual sense of the word, or only that kind of it the ten- 

 dency of which is confined to an increase in the number of 

 feet. 

 These are the Aptera of Linnaeus, and comprehends three 

 classes, viz. Crust acea, Arachnida, and Ametabola, which 

 would be termed Radii by M. Fries. 

 Trne Insects, being all subject to that kind of metamorpho- 

 sis which has a tendency to give wings, to the perfect or 

 imago state, but never more than six feet. 

 Theseare the Ptilota of Aristotle, and should, according to 

 M. Fries, be termed the Centrum of Annulose Animals.
