134 THE HISTORY OF CREATION, 
reasons previously given. Hence, if we here leave them out 
of the question, we may accept two main classes or provinces 
of real Protozoa, namely, Egg animals (Ovularia) and Germ. 
animals (Blastularia). To the former belong the three 
classes of Archezoa, Gregarine, and Infusoria, to the latter 
the two classes of Planzeads and Gastrzeads. 
The first province of the Protozoa consists of the Egg 
animals (Ovularia); we include among them all single- 
celled animals, all animals whose body, in the fully 
developed state, possesses the form-value of a simple 
plastid (of a cytod or a cell), also those simple animal forms 
whose body consists of an aggregation of several cells per- 
fectly similar one to another. 
The Archaic animals (Archezoa) form the first class 
in the series of Egg animals. It contains only the most 
simple and most ancient primary forms of the animal 
kingdom, whose former existence we have proved by means 
of the fundamental law of biogenesis; they are, (1) Animal 
Monera ; (2) Animal Amcebze ; (3) Animal Synamcebze. We 
may, if we choose, include among them a portion of the 
still living Monera and Amcebx, but another portion (ac- 
cording to the discussion in Chapter XVI.) must on account 
of their neutral nature be considered as Protista, and a third 
portion, on account of their vegetable nature, must be con- 
sidered as plants. 
A second class of the egg animals consists of the Grega- 
rines (Gregarinz), which live as parasites in the intestines 
and, body-cavities of many animals. Some of these Grega- 
rines are perfectly simple cells like the Amcebze ; some form 
chains of two or three identical cells, one lying behind the 
other. They differ from the naked Amcebz by possessing
