290 NATURAL SCIENCE. Oct., 1895. 



The death of Marshall McDonald, which occurred on Sep- 

 tember I at Washington, robs the United States Fish Commission of 

 an able and valued officer. When Professor Spencer Baird died, 

 the post was temporarily occupied by Professor Brown Goode, and 

 subsequently accepted by Mr. McDonald, who was chief assistant 

 commissioner. The appointment was a successful one, and the 

 department over which Mr. McDonald presided has become one of 

 the most important economic bureaus of the Government. Mr. 

 McDonald was the inventor of a stairway to enable salmon to ascend 

 rapids, and his services have been of considerable value to the 

 progress of pisciculture in the United States and elsewhere. The 

 office of Fish Commissioner is now a most important one, and it is 

 hoped that one of Mr. McDonald's assistants will be chosen to 

 succeed so capable an administrator. 



Among others who have recently passed away, we notice Dr. R. 

 Krause, the anthropologist, at one time of the Museum Godeffroy in 

 Hamburg, who died at Schwerin (Mecklenburg) on July 25 ; Dr. 

 Felix Hoppe-Seyler, Professor of Physiological Chemistry at 

 Strassburg, who died on August 1 1 at Wasserburg on the Bodensee, 

 aged 70 years; and Dr. Thomas Henderson Chandler, dean of the 

 Harvard Dental School, who died on August 27, at the age of 71.
