organization in which there is a sharp differentiation of nucleus 

 and cytoplasm, and if organisms such as Bacteria, in which there 

 is scattered chromatin but no definite nucleus, were not termed 

 cells. If, however, the term " cell " is too compromised to be 

 restricted in this manner, then two terms should be coined to 

 denote these two primitive grades or types of organization, the 

 one without a nucleus, as in Bacteria and allied forms, the other 

 possessing a nucleus, as in Protozoa and the cells of animals and 

 plants. 



I have ventured here to express definite views upon some very 

 controversial and speculative subjects. It is not to be expected 

 that everybody should be of one mind in such matters ; but what- 

 ever may be the views taken, I think everyone will agree as to 

 the fundamental importance of the study of the living substance 

 in its simplest forms, and I desire, therefore, to express my strong: 

 appreciation of the sagacity and foresight, no less than the 

 generosity, of the I'ounder of the Trail Award, and my thanks to 

 him for the stimulus and encouragement which he has given to 

 such investigations. 



The General Secretary then laid Obituary Notices of deceased

OBITUAEY NOTICES. 



Alexaivder Agassiz. — The death of Alexander Agassiz leaves a 

 real gap in the world of scientific oceanography Avhich no man of 

 our own generation can adequately fill. He died on March the 

 27th, 1910, on the steamer ' Adriatic,' en route from England to 

 America, at the age of seventy-five. Alexander Agassiz was the 

 son of Louis Agassiz, Professor of Zoology at Harvard. He 

 accompanied his father to America in 1849, at the age of foui'teen 

 years, and graduated in Engineering and Zoology. His first 

 serious work was on the Pacific Coast Survey of Ameinca, but in 

 1849 and in 1851 he had already served an apprenticeship under 

 his father on the Atlantic sea-board and off Elorida. He spent 

 some years in assisting his father in developing the Museum of 

 Zoology at Harvard : and he became well known for his ability 

 not only in Zoology but in the management of affairs. In 1866 

 he undertook the development and management of the Calumet 

 and Hecla Copper Mine on Lake Superior. This was at that time 

 almost a worthless property : it has since become the greatest 

 single copper mine in the world, and has paid in dividends, since 

 that date, upwards of =£25,000,000. His association with this mine 

 led to the foundation of a fortune which enabled him to follow his 

 natural bent towards Marine Biology. He retired from active 

 work in connexion with the mine after about five years, but he 

 retained his interest in it as President or Director until his 

 death. 



Professor Agassiz will be best remembered by his numerous
