Thunder and Lightning, as its title indicates, deals with the most startling phenomena of nature. The writings of the author, M. De Fonvielle, have attracted very general attention in France, as well on account of the happy manner in which he calls his readers' attention to certain facts heretofore treated in scientific works only, as because of the statement of others often observed and spoken of, over which he appears to throw quite a new light. The different kinds of lightning—forked, globular, and sheet lightning—are described; numerous instances of the effects produced by this wonderful agency are very graphically narrated; and thirty-nine engravings, nearly all full-page, illustrate the text most effectively. The volume is certain to excite popular interest, and to call the attention of persons unaccustomed to observe to some of the wonderful phenomena which surround us in this world.

CRITICAL NOTICES.

"In the nook before us the dryness of detail is avoided. The author has given us all the scientific information necessary, and yet so happily united interest with instruction that no person who has the smallest particle of curiosity to investigate the subject treated of can fail to be interested in it."—N.Y. Herald.

"Any boy or girl who wants to read strange stories and see curious pictures of the doings of electricity had better get these books."—Our Young Folks.

"A volume which cannot fail to attract attention and awaken interest in persons who have not been accustomed to give the subject any thought."—Daily Register (New Haven).
