countries. Several years ago his son, Dr. Heinrich Fresenius, assumed the active 

 direction of the analytical laboratory in Wiesbaden and the work will be continued 

 along the lines laid down by its founder. 



Prof. P. Schiitzenberger died June 28 in Paris, aged 67 years. He was a native of 

 Strassburg and spent some years in teaching in that city. Afterwards he was assist- 

 ant director of the Sorbonne Laboratory in Paris, head of the chemical department 

 of the College of France, and since 1876 professor of chemistry in the latter institu- 

 tion. He was elected head of the Paris Municipal School of Chemistry and Pbysics, 

 and was a fellow of the Academy of Medicine aud of the Academy of Sciences. He 

 contributed largely to the subject of organic chemistry and devoted especial atten- 

 tion, among other subjects, to digestion and fermentation. 



Julius Sachs, the eminent botanist, was born at Breslau, October 2, 1832, and 

 died at Wiirzburg, May 29, 1897. His first official post was privat doceut at Prague. 

 Later he was professor of botany at the Agricultural Institute at Poppelsdorf and 

 afterwards at the University of Freiburg. In 1867 he was called to the professorship 

 of botany at Wiirzburg, which position he held at the time of his death. He was 

 one of the foremost of modern botanists as an investigator and teacher, especially 

 in physiological botany, and a prolific writer on botanical subjects. His "Text- 

 book" is recognized as a standard work, and embodies a great amount of original 

 research. 



Martin Wilckens was born at Hamburg in 1834, and died at Vienna in June, 1897. 

 He devoted many years to the study of agriculture, and with the assistance of the 

 Prussian Government made a large number of investigations, principally in the line 

 of animal production. In 1872 he was called to Rostock as professor of agriculture, 

 and later in the same year went to Vienna as professor of animal physiology and 

 animal production in the Imperial Agricultural High School. He has published 

 numerous works on agricultural topics, especially animal physiology and animal 

 production, the most important of which is perhaps " Grundriss der landwirthschaft- 

 liclien Haustierlehre,'' issued in two volumes in 1888-'89. In 1889 Professor Wilckens 

 made an extended journey through the United States for the purpose of studying 

 American agriculture, visiting many of the experiment stations. The results of 

 this study are given in a book of 292 pages, published in 1890, entitled " Norda- 

 merikani8che Landwirthschaft."
