NATURAL Si TENCJC. — ‘ ‘ Tli is second volume of the Cambridge Natural History is certain to prove a most 
welcome addition to English Zoological literature. It, deals with a series of animal groups, all deeply interesting to 
the specialist in Morphology ; some important from their economic relations to other living things, others in their 
life-histories rivalling the marvels of fairy-tales. And the style in which they are here treated is also interesting : 
history and the early observations of the older writers lend their charm ; accounts of habits, and mode of occurrence, 
of life, in a word, from the cradle to the grave, are given in ample detail, accompanied by full references to modern 
and current literature. The whole is admirably illustrated.”
