 bacilli. My specimens evidently belong to the latter class. 

 They are identical with those figured by Dr. Klein in his writings

STEPHANODISCUS NIAGARA. 



Mr. Edward G. Day : " Stephanodiscus Niagarce, a diatom of

 supply of water from the lake. They are easily procured by

 more clearly, than when Canada balsam is used. The work of
