surpassingly grand and wonderfully minute. Th 
other analogies in this table are too obvious to require 
pointing out. 
(58.) Let us now compare the subgenera of Sy 
vicola with those of Parus. It will be remembered, 
that these two are the typical groups or genera of the 
subfamily Pariane, and that each contain five sub- 
genera. Now, if these are disposed in their natural 
series, each of these subgenera will mutually pos- 
sess a strong and peculiar resemblance to each other, 
so that, in fact, the subgenera of Sylvicola will con- 
tain representations of the subgenera of Parus. To 
this test, every group or genus, thought to be natural, 
must be brought. Now, that this is not only true in 
regard to the birds in question, but wonderfully regular 
and beautiful, when developed, the ornithologist will 
perceive, on studying the following table : —

(59.) To pursue this subject further would be 
almost needless, since the test we have thus applied to 
the contents of both groups, demonstrates their natural 
arrangement. By referring to the preceding table of 
the analogies of the five subgenera of Sylvicola, the 
naturalist will perceive that, in these two genera, nature — 
preserves the same laws by which she has regulated her — 
primary divisions of matter. _We have in each chee, 
or 
primary circles, which, when compared with the three
