From this view it is evident, that the relations of the 

 parts of fructification afford the foundation of arrangement. 

 These relations consist in the Number, the Insertion, the Dif- 

 ference of Length, the Union and the Separation of the male 

 parts, as w^ell considered in reference to themselves, as in 

 respect to the female parts. A preference is given to the 

 male parts, which is less founded in nature, than apparently 

 rendered necessary by the circumstance that, besides being 

 commonly in greater number, they present also more varieties. 

 Nature seems, upon the whole, to have given less constancy 

 to the Numerical proportion, than to the Forms, the Situation, 

 the Union, and the different Lengths of the sexual parts. 

 The finding of plants in those catalogues which have been 

 arranged after this system, is very much aided by the simpli- 

 city of the principle ; yet, in such researches, we must attend 

 to all the other relations, beside the number of the parts.

In judging of this system, we cannot speak of its want of 

 conformity to nature, because, from the very fact of its being
