induced the legislature of Massachusetts to grant a 

 large measure of support. Legally, it might belong to 

 the Harvard Corporation, but it was in all essentials 

 a public insitution, free to those who cared to make use 

 of it. 



11. In 1848 Agassiz visited the shores of Lake Journeyto 

 Superior, and in 1850 the Florida reefs. In 1865-1866 



he went with his wife and a company of young natural-

 They are still preserved at the Museum of Compara-

 ologists. 



In 1871-1872 Agassiz went in the Coast Survey Hassier 

 vessel Hassier to California by way of Cape Horn. exped 

 It was a long voyage, and his health had been poor, 

 but he was delighted with the opportunity to see so

 but once more his splendid energy declared itself. He
