254 CONCLUSION. 



ers, Scratchers, Runners, and Swimmers ; and that the 

 Reptiles, Batracliians, and Pishes, the Insects, Crusta- 

 ceans, and Worms, the Cephalopods, Gasteropods, and 

 Acephals, and the Echinoderms, Acalephs, and Polyps, 

 are also similarly divided into groups. Naturalists 

 call these groups Orders. The Orders are divided 

 into Families, — for example, the Order of Birds of 

 Prey is divided into the Family of Vultures, the 

 Family- of Falcons and Eagles, and the Family of 

 Owls. Families are divided into Genera, — for ex- 

 ample, the Family of Falcons is divided into true Fal- 

 cons, Hawks, Eagles, &c. Genera are divided into 

 Species, — for example, the Genus of true Falcons is 

 divided into the Peregrine Falcons or Duck Hawks, 

 Pigeon Falcons or Pigeon Hawks, Sparrow Falcons or 

 Sparrow Hawks, &c.

But the words of a book cannot fitly describe the

 eyes and study them in the world about us. We may

 lake, in every pool and ditch and bog, and in every 

 glass of water from the spring. Every summer's day 

 brings scores of beautiful winged forms, and on every
