fertile valleys were chains of lakes and morasses, which have been drained 

 and converted into alluvial land by the natural deepening of the river

 and anon crack with a loud noise in our domestic hearths. — P. S., White-

Classification of Animals. — In order that our readers may have the 

 opportuniiy of examining the latest classification of animals, as expounded 

 by the most advanced school of zoologists, the following table is inserted, 

 which is adapted from the classification of Professors Huxley and E-eay 

 Greene (Jukes's 'Manual of Geology,' pp. 376 and 710). The groups to 

 which an li. is attached were classified by Cuvier under Madiata.
