Returning to the subject again a few years later, with a 

 critical series of twenty experiments, each of three, live, ten, 

 fifteen, or even twenty flasks, used by way of checks and com- 

 parisons, — a rigorous experimenter would have been satisfied 

 when he had proved that sealed solutions subjected to a heat 

 of at least 212° for from one to four hours, became the seat 

 of infusorial life, at least of such as Vibrios, Bacterians and 

 Monads, while all infusoria having the faculty of locomotion 

 were shown by a special series of experiments to lose this at 

 a temperature of 120°, or at most 134° Fahr. But Prof. 

 Wyman carried the boiling up to five hours, and in these 

 flasks no infusoria of any kind appeared. The question of 

 abiogenesis stands to-day very much where Prof. Wyman 

 left it seven years ago. 



I must omit all notice of the ethnological work which has 

 occupied his later years, merely referring to the seven Annual 

 Reports of the Trustees of the Peabody Museum of Ameri- 

 can Archaeology and Ethnology, of which he was curator. 

 The last of these, issued just before the writer's death, con- 

 tains the principal results of his investigation of the human 

 remains he collected in the shell-heaps of East Florida, and 

 convincing evidence of the cannibalism of those who made 

 them. A fuller memoir, embodying all his observations of 

 the last six winters upon the Florida shell-mounds, was sent 

 to th'e printer just before he died. 



The thought that fills our minds upon a survey even so 

 incomplete as this is : How much he did, how well he did it 

 all, and how simply and quietly ! We knew that our asso- 

 ciate, though never hurried, was never idle, and that his 

 great repose of manner covered a sustained energy ; but I 

 suspect that none of us, without searching out and collecting
