Observations on the Table of Analogies. 
It is not assumed that the subjects selected and 
named at the head of each of the foregoing columns 
are, even nearly, all which might have been chosen 
for a synoptical exemplification of analogies between 
different classes of animals and the vegetable world 
in general. Nor will it be contended, against any 
precise critic, that the columns are arranged in the 
best order, or that all the instances are certain. 
The use of synoptical tables in every branch of 
science is obvious. They afford great aid to me- 
mory: but also on frequent review they suggest 
continually to the inquiring mind new traces of un- 
discovered relations. 
Differences for the most part strike the senses 
readily. Similitudes require a second thought ; per- 
haps a third. Analogies, or the mutualities of rela- 
tions, demand a fourth, a fifth, or a sixth. Differ- 
ences are numerous as the possible objects of the 
senses or of thought. Similitudes and analogies are 
limits of differences; the indices of groups, of dis- 
tinct assemblages, the standards or insignia which 
designate divisions as in military arrangement, bri- 
gades, regiments, companies, &c. 
Infinite diversity indicates infinite extent of power. 
Innumerable adaptations to good display immeasur- 
able goodness in the Power which has ordained the 
adaptation. 
Universal analogy, as already observed, demon-
