stituents; and Chapter IV., to animal constituents. Chapter V. 

 presents a treatise on micro-organisms, Chapters VI., VII., VIII., 

 discuss water-supplies, natural purification, and artiBcial purifi- 

 cation, and Chapter IX. describes eight different systems for cen- 

 tral filtration. An appendix, divided into two sectigns, closes the 

 book. Section A treats of the origin and home of cholera. Sec- 

 tion B presents four simple qualitative tests for impurities in 

 drinking-water. 



— Babyhood for June considers the seasonable question of what 

 to do with children in the city and country, and how to provide 

 for their welfare generally, during the heated term; and a medi- 

 cal paper by Dr. Walter Mendelson, on " Practical Directions for 

 Sterilizing Milk," offers an account of this important subject. 



— Several new leaflets are to be added to the general series of 

 "Old South Leaflets," published by D. C. Heath & Co., Boston. 

 All of them are connected with the English Puritan period, and 

 are of value in the study of the development of our own political 

 liberty and of our political system. They include the " Petition 

 of Eight," presented by Parliament to King Charles in 1628 ; the 

 "Grand Remonstrance;" the "Solemn League and Covenant," 

 which gave the name of '■ Covenanters" to the Scottish Protes- 

 tants; the '' Agreement of the People;" the " Instrument of Gov- 

 ernment," under which Cromwell began bis government; and 

 " Cromwell's First Speech to his Parliament." These leaflets fur- 

 nish these original documents, heretofore almost inaccessible to 



the mass of the people, for the few cents covering their cost. 

 There are now nearly thirty in the series. 



— Macmillan & Co. will shortly publish " Studies of the Gods 

 in Greece at Certain Sanctuaries Recently Excavated," by Mr. 

 Louis Dyer, formerly assistant professor in Harvard University. 

 The book represents a course of lectures delivered by Mr. Dyer at 

 the Lowell Institute, Boston ; but the material has undergone very 

 thorough revision, and notes and appendixes have been added on 

 special points. The same firm are also going to publish "Brown- 

 ing as a Philosophical and Religious Teacher," by Professor Jones 

 of University College. This work deals with Browning, not sim- 

 l^ly as a poet, but as the exponent of a system of ideas on moral 

 and religious subjects, which may fairly be called a philosophy. 



— In the June number of The Political Science Quarterly Pro- 

 fessor Burgess of Columbia College discusses the international and 

 constitutional questions raised by the recent controversy with 

 Italy. He holds that a foreign government whose subjects have 

 been wronged is entitled to demand that the United States Gov- 

 ernment should initiate proceedings against wrong-doers in the 

 United States courts. He finds that the Constitution vests in the 

 Federal Government the power to do this, but that Congress has 

 not passed the necessary statutes to make this power effective. 

 Horace White writes on bimetallism in France, showing that all 

 attempts to keep the two metals in equipoise have proved unsuc- 

 cessful. F. M. Drew gives an account of the organization and
