Necrology.— Prof. Max von Pettenkofer, renowned for his investigations in medi- 

 cine, hygiene, and physiology, died by suicide at Mvmich February 10, 1901, at the 

 age of 82 years. Professor Pettenkofer was born December 3, 1818, at Lichtenheim, 

 Bavaria. He graduated in medicine at Munich in 1843, and three years later became 

 an associate professor in the medical faculty at Munich, being advanced to full pro- 

 fessorship in 1853. In the meantime he had succeeded his uncle as director of the 

 court pharmacy at Munich, which under him became in effect a scientific labora- 

 tory. Early in his career Professor Pettenkofer became interested in public hygiene, 

 and the results of his studies aroused much popular interest, leading to the establish- 

 ment of chairs of hygiene at the higher educational institutions in Bavaria. One of 

 his greatest achievements was the study of cholera, and the hygienic and sanitary 

 measures necessary to control the disease and prevent its spread. This work led him 

 to studies of typhus, and in general those diseases in whose dissemination soil, water, 

 and air are important factors. He founded the Archiv fiir Hijgiene, and was for a 

 long time coeditor of the Zeitschrift filr Biologic, both of which have for years been 

 leading periodicals in their lines. To those interested in problems relating to the 

 nutrition of man and animals, Pettenkofer' s most interesting investigations had to do 

 with the respiration apparatus. In 1862, a description of his apparatus, designed 

 for experiments with man, was published, and the result of experiments with it 

 appeared at frequent intervals later. The apparatus differed from earlier forms in 

 many important particulars. It was adapted for use in experiments with farm 

 animals by a number of German investigators, while a form suited to experiments 

 with dogs and small animals was devised by Voit, who was long associated with 

 Pettenkofer in this line of research. The results obtained by Pettenkofer and his
