    os ' WOTES AND 2. Simia. 3. Lemur. 4. Vespertilio. Purton'’s Translation, vol. 1. Several new systems have been formed, the most esteemed of which are those of Blumenbach and Cuvier. ° ‘ Blumenbach’s is as follows : | There are two grand divisions of animals ; ; those which have a vertebral col- umn and red blood and those which have no vertebra and are white blooded. He subdivides vertebra] animals into the warm and cold pe eaie and makes two classes of warm blooded animals : 1. Mammalia. Pia . 2. Birds. ss es, | And he distributes the class mammalia into sIx orders : 1. Bimanum ; two handed animals. 2. Quadrumana ; four handed animals. : 3. Bradypoda ; slow moving animals. : 4. Cheiroptera ; having the fingers cues laa for the expansion of a mémi- brane, which acts asa wing. 5. Glires ; gnawing animals. 6. Fere ; predaceous and carnivorous animals. For all the outlines see the Introduction to Blumenbach’s Short System of Comparative Anatomy, by William Lawrence. Cuvier, also, divides the animal kingdom into two great families ; 1 .gAnimals which have vertebre and red blood ; 2. Animals without vertebra, almost all of which have white blood. He subdivides vertebral animals into two es ; those we warm blood and those with cold blood. Each of these two branches is divided into two classes. Those of the animals with warm blood are, 1. Mammalia. 2. Birds. _ The classes of vertebral animals with cold blood are, 1. Reptiles. | 2. Fishes. * fhe invertebral animals ought to be divided into five elasses : 41, Mollusca. 2. Crustacea. 3. Insects. 4. Terrestrial worms and leeches.
