Natural History
In order to understand any science rightly, it needs that the student should proceed to its contemplation in an orderly manner, arranging in his mind the various portions of which it is composed, and endeavouring, as far as possible, to follow that classification which best accords with nature.
1 st The Vertebrates include Man and all the Mammalia, the Birds, the Reptiles, and the Fish. The term Vertebrate is applied to them because they are furnished with a succession of bones called "vertebrae," running along the body and forming a support and protection to the nervous cord that connects the body with the brain by means of numerous branches.
2nd. The Mollusca, or soft -bodied animas , include the Cuttle-fish, the Snaills,Slugs,Mussels,&c. Some ofthem possess shells, while others are entirely destitute of such defence. Their nervous system is arranged on a different plan from that of the Vertebrates. They have no definite brain ,and no real spinal card , but their nerves issue from constain masses of nervous issue from crtain massesof nervous subsstance techinically called ganglia.
3rd The ARTICULates, or jointe animals, from an enormously large division,comprising the Crustaceans, such as the Crabs,and Lobsters, the insects, Spiders, Worms,and very many creatures so different from each other,that it is scarcely possible to find any common charactistics.
4th The next division, that of the RADIATED animals , is so named ona account of the rediated or star-like from of the body, so well exhibitedin the Star-fishes and the Seaanemones.
5th.The PROTOZOA, or primitive animals, are as far we know,devoid of internal organs or external limbs, and in manyof them the signs of life are so feeble,that they can scarcely be distingushed from vegitaable germs. The Sponges andInfusorial Animalicules are familiar exmples of this division.
By all means this book is of great worth to the student in aspiration of Natural Historical livelihood. in its original and natural habitate. This book is of great use for the students of Natural sciences and as an reference book for Animal lovers.
The Book is further divided in to Three classical sections wide 1. Mammalia 2. Birds. 3. Insects
