18 FHE8fI WATKH LIFE. 



form, but the conditions were not favorable in some way and 

 they were unable to progress further and so died by starvation 

 or drowning. 



During the Christmas holidays Nos. 4 and 5 were allowed to 

 freeze solid, and after having been thawed out were again ex- 

 amined. 



No. 4 was examined on Januar\' 26th, 1905. 

 All that was found were the following : 



Nav- Subgigus, some recent and lots of frustules, 

 Nav. Viridis, " '' '' " " 



Many parameceidse. Nothing more, and all vegetation gone 

 except a little of the water grass and some Dicholymse. 

 No. 5 was examined Feb. 7th, 1905 — 

 Nav. Subgigas, frustules only, 



'■ Viridis, 

 Cymbella gastroides, frustules only. 

 There were also many vorticellse. 



1 Cyprid, quite lively, 



8 or 10 Rotifera vulgaria, 



2 or 3 specimens of Hydrachne Belostoma. 



Many chydori shells, but none recent; found one foot separ- 

 ate from its shell, showing spurs and terminal nail and out- 

 lines perfectly shown. I should say that there is a large bony 

 plate in the leg of the chydorus, representing the skeleton in 

 the higher animals. There was one animal also that came into 

 the field but disappeared like a flash and could not be found 

 again. I should imagine from the motion it might be a cyclops. 



All vegetation had disappeared from the basin except water 

 grass, which still seems to flourish, Dichelyma and Leraua 

 minor.
