Plate XXX., tig. .5, Eozoon canadense, reputed canal system of Eozoon; fig. 6 the same. 

 Both stones from which the slides were taken were collected by me in Little Nation. 

 Let one compare the canal system of the nummulite fig. 3 with this reputed canal 

 system! Figs. 3 and 5 should be the same thing.
