200 ON SYSTEMATIC ZOOLOGY. 
this table of affinities, however confused it may appear, 
or subramose, as it is termed, coincides with the tabular 
view which I have laid before the public.* We have only 
to join the Radiata to the Cirripeda, and the Annalides 
to fishes, and Lamarck’s table of affinities, with scarcely 
any alteration, becomes precisely the same as mine.” It 
is therefore clear, that the first perception of that cir- . 
cular series of affinity which pervades the animal king- 
dom was gained by Lamarck in the year 1815. But this 
was done without the least suspicion arising, on his part, 
that the circularity of natural groups was the first prin- 
ciple of natural arrangement. His studies, in fact, did 
not extend to vertebrated animals; but he had an in- 
tuitive perception of natural affinities; and by follow- 
ing these he traced the natural series, without, however, 
perceiving that it assumed the disposition of a circle, 
which the vertebrated animals would render complete. 
That this fact may be more apparent to our readers, and 
that we may justify our opinion that the system of this 
able but fanciful zoologist was eminently natural, we 
here subjoin the table in question : —

admirable arrangement of the testaceous mollusca orshells, 
a department in which he created so great a reformation
