Certain Protozoa are common to all the soils examined from

 as well as the Ciliate, Cyclidium glaucoma. 



Different species of Amoebiie occur in different types of soils. 



The Herpetomonas {H. terricola) was observed only in

 that the total number of individual Protozoa was greater in fertile 

 than in infertile soils, as shown by water cultures.
