 Van Brunt, C. — Removing air from Diatoms. 



[The frustules are dried on the cover-glass, which is then placed on a slide, 

 diatoms up, and plain balsam is dropped upon them. By heat the balsam 

 is caused to flow round the diatoms. It does not replace all the air within 

 them, but by alternately heating the balsam up to the boiling-point and 

 then cooling it, two or three times, all the air can be expelled.]
