 [Davis, G. E.] — Our suspended publication. 



[" No sooner i.s one month's number out than the worry of the next com- 

 " mences. Few people are awiirc of the vast amount of work required to 

 " keep even a small journal like this in motion." In our own case, we 

 should be very well contented if the " worry of the next number " only 

 commenced when the preceding number was out. — Ed. J.K.IM.S.]

 Davison, J. — Naiicula cuspidata as a test-object. 



[Transverse strias can be shown by a good 1/4 in. object-glass, but a good 

 1/8 fails to show any lungitudinal strife. With a good 1/16 and careful 

 illumination, however, both sets of striae can be si en. The donble set of 

 striae is much easier shown when the frustules are mounted dry or in 

 media less transparent than balsam, such as styrax.]
