yet it may be urged that this determinate number of 
nine, in the different ranks of circular groups, is a 
theory too important to be taken on the testimony 
of one naturalist only, interested in strengthening a 
theory of his own, and, therefore, with every wish 
to be accurate, still peculiarly liable to error. Now 
we shall at once annul this objection, although it 
rests on no demonstrative evidence, by producing 
the unpremeditated evidence of one who had no idea 
of the law in question, but merely drew up his ob- 
servations to illustrate a particular group of animals 
in a totally different class. Mr. Macleay’s views on 
the number of circular groups which exist, before 
he arrived at that of the genus Scarabceus, has thus 
been stated by himself ; and we shall now compare 
them with those of the genus Todus.
