Le Diatomiste, Journal special s'occupant exclusivement 

 des Diatomees et de tout ce qui s'y rattache. — It is a pleasure to 

 be able to call attention to a periodical as valuable as this and 

 devoted exclusively to the study of the Diatoms. The man that 

 should even think of issuing such a magazine in this country 

 would be looked at askance, and left to enjoy his publication 

 alone ; but in Europe such things appear to be done differently. 

 " Le Diatomiste " is a quarto, published every three months, ex- 

 quisitely illustrated with photo-gravures, and apparently well 

 supported by the diatomists of France and of other European 

 <30untries. No American student of the Diatoms can afford to 

 neglect it, especially since it is now publishing a monograph of 

 Pleurosigma, profusely illustrated, and describing every known 

 species. The magazine is ably edited by M. J. Tempere, 168 Rue 

 St-Antoine, Paris, the subscription price being only 15 frauds. 

 The journal merits the greatest success. 



Six Centuries of Work and Wages — A History of English 

 Labor— By J. E. Thorold Rogers, M. P.— With Charts and Ap- 

 pendix by the Rev W. D. P. Bliss. — Introduction by Richard T. 

 Ely, Ph.D.— Price 25 cents.— The Humboldt Publishing Co., 

 Astor Place, New York. 



This is the story of the struggle of the English poor against 

 the avarice of priest and king, landlord and capitalist ; a story 

 told by the records of thousands of court rolls, and stewards' 

 accounts, compiled by unconscious historians that little dreamed 

 of the tale the figures they so patiently added up would one day 

 be made to tell. From the beginning of the thirteenth century, 

 when almost every one not only possessed land but cultivated 

 it ; when a landless man was looked on as an outlaw and a 

 stranger; when the use of the common pasture was without 

 stint, and the arable land of the manor was usually communal ; 

 from that remote date to modern times, Prof Rogers conducts 

 the reader through the successive stages of a drama whose 

 motive was the cheapening of labor for the benefit of the mo- 

 nopolist.
