structural characters on which to unite them, 
and the groups so founded generally correspond 
with the combinations suggested by their ap-

By a like process Lamarck combined animals 
“into families. His method was adopted by 
French naturalists generally, and found favor 
especially with Cuvier, who was particularly 
successful in limiting families among animals, 
and in naming them happily, generally selecting 
names expressive of the features on which the 
groups were founded, or borrowing them from 
familiar animals. Much, indeed, depends upon 
the pleasant sound and the significance of a 
name ; for an idea reaches the mind more easily 
when well expressed, and Cuvier’s names were 
both simple and significant. His descriptions 
are also remarkable for their graphic precision, 
-» giving all that is essential, omitting all that 
is merely accessory. He has given us the key- 
note to his progress in his own expressive lan- 
guage :— °
