and was a work in which he took great pride. It will remain as a 

 monument to his industry and his broad grasp of the subject. 



Public recognition of the services and the place occupied by 

 Grandeau are evidenced by the honors and offices conferred upon him. 

 In addition to the positions already mentioned, he was a member of 

 the Superior Council of Agriculture, of the National Societj^ of 

 Agriculture, and vice president of the Society for the Encouragement 

 of Agriculture in his own country, and was also elected to member- 

 ship in the Royal Society of England, the Imperial Agricultural 

 Societ}^ of Moscow, the Royal Agricultural Academies of Turin and 

 of Sweden, and many others. In 1900 the French Government con- 

 ferred upon him the order of Commander of the Legion of Honor, 

 and in 1908 the National Society of Agriculture awarded him a gold 

 medal in consideration of the services rendered by him for more than 

 50 years, an honor which the history of his active life highly merited. 



Oskar Kellner, director of the agricultural experiment station at 

 Mockern, Germany, was born May 13, 1851, at Tillowitz, near Falk- 

 enberg, in the Prussian Province of Silesia. Following the Franco- 

 Prussian "War, in which he took part, he studied chemistry and the 

 natural sciences at the universities of Breslau and Leipsic, taking 

 special work at the latter institution under Knop and Sachsse, and 

 made his doctorate at Leipsic in 1874. For two years following he 

 was assistant in the experiment station for animal physiology at 

 Breslau, under Hugo "Weiske. This position gave him opportunity 

 to enter upon the field of investigation in which he was later to make 

 such notable contributions. 



In 1876 he went to the experiment station at Hohenheim, where 

 under Emil von Wolff, one of the founders of the modern theories of 

 animal nutrition, he continued investigations in this line, one of his 

 notable studies on the effect of muscular activity on the metabolism 

 of the horse being a product of that period. It is an interesting and 

 significant fact that at this early date, four years before the publi- 

 cation of Rubner's epoch-making paper on the replacement values 

 of the principal organic nutrients and nine years before Lehmann, 

 Zuntz, and Hagemann's first respiration experiments on the horse 

 appeared, we find Kellner investigating the utilization of the poten- 

 tial energ}^ of carbohydrates and of fats in work production, and 

 devising a general experimental method for this j^urpose, substan- 

 tially according to which the subsequent experiments at Hohenheim 

 were made. 



From 1881 to 1893 Kellner was professor of agricultural chemistry 

 in the University of Tokio, being likewise technical adviser in the 

 ministry of agriculture and commerce. Here he continued his re- 

 searches, publishing a long series of papers in cgllaboration with his
