10 Mr. W.S. Macueay on the Comparative Anatomy 
ledge of these several truths by the observation of Nature alone ; 
so I first saw their dependence upon each other, their general 
application, and their necessary derivation, from the practice of 
studying the method in which animal structures vary. How far 
shadowy and unconnected notions on the above subjects may 
affect the claims of the Hore Entomologice to public attention I 
shall not pretend to determine ; but it is my duty, on the other 
hand, to say, that I was surprised on looking lately among the 
notes and explanations of the plates (page 181), at the end of a 
work published at Moscow in 1808 by Professor Fischer, and 
entitled “‘Tabule Synoptice Zoognosia in usum Auditorum edite,” 
to find the following remarks: ‘“ L’auteur trouve dans la Nature 
organisée une opposition remarkable qui pourroit étre exprimée 
par deux cercles en mouvement, qui se touchent ou qui se croisent 
en deux endroits.

magis patescunt.”—Tab. Aff. Anim. p.37. Such are the words of a naturalist con- 
summately versed in the observation of facts, as well as in the speculations of philo- 
sophy ; but whose learned work is a singular example of the consequences of mistaking 
relations of analogy for those of affinity, inasmuch as it presents us at the same time 
with an inexhaustible mine of information, and an almost inextricable mass of con- 
fusion. I ought in this place further to mention, that Hermann (p. 8.) cites the fol- 
lowing words from Eusebius Nieremberg, Nat. Hisé. lib. iii. c. 3.— Scilicet per con- 
textum Natura assurgit paulatim et sine saltu velut continua procedit trama. Nullus 
hiatus
