COLLECTING AND PRESERVING MICROSCOPIC PLANTS. 



Small plants like Desmids, Diatoms, etc., may be preserved in 

 water, in homeopathic vials, provided a drop of carbolic acid is 

 added to each bottle of material. In this way they will keep for a 

 long time with very little change of color and contents.
