To manage this little feeding organism, with its wondrous instinct and capacity of imbibition, is the first great question after that of race is settled. Shall the mother's blood continue to flow through its fast-throbbing heart, and all the subtile affinities that bind the two lives be continued until reason and affection take up the chain where the link of bodily dependence is broken? Or shall it cleave no more to her bosom, but transfer its endearing dependence to a stranger, or learn to call a bottle its mother? These are some of the questions learnedly, and yet familiarly, discussed in M. Donné's book. He has laid down many excellent rules for the physical and moral management of the infant, which the young mother can readily learn and put in practice. For the physician, his work contains many interesting facts with reference to the quality and the microscopic appearances of milk, as obtained from various sources and under different circumstances. On one or two points our American experience would somewhat modify the rules commonly accepted in Paris. The nurse from the French provinces is evidently a different being from our Milesian milky mothers. So, too, the rules given by our own venerable and sagacious observer, Dr. James Jackson, as to the period of separating the infant from its mother or nurse, should be borne in mind, as laid down in his admirable "Letters to a Young Physician." But there is a great deal of information applicable to children and their mothers in all civilized regions; and as we wish to start fair with the next generation, we are very glad to have so intelligent a guide for the management of our infant citizens. _Street Thoughts._ By the Rev. Henry M. Dexter, Pastor of Pine-Street Church, Boston. With Illustrations by Billings. Boston: Crosby, Nichols, & Co. 1859. If a profusion of introductory mottoes were any indication of the excellence of a book, this volume would be indeed a _chef-d'oeuvre_. On the page usually devoted to the Dedication, we have no less than six more or less appropriate quotations: a Greek one from Julian, a Latin one from Quintilian, a dramatic one from Shakspeare, a metrical one from Young, a ponderous philosophical one from Dr. Johnson, and a commonplace one from Bryant. In consideration of the number and learnedness of these certificates of character, we approach the lucubrations of the Reverend Mr. Dexter with profound respect.
