 of considerable refracting power, and besides the latter a great 

 number of oleaginous drops, soluble in ether. It manifests very 

 marked amoeboid motions, and takes up particles of carmine, etc."

143 (ii. 70). The five first stages in the evolution of the 

 animal body, which are compared in Table XVII., and which 

 are common to Man and all higher Animals, are established 

 beyond all doubt as existing in the Ontogeny of most extant 

 animals. As Comparative Anatomy shows that corresponding 

 form-stages yet exist in the system of the lower animals, we 

 may assume, in accordance with the fundamental law of Biogeny, 

 that similar forms existed phylogenetically as most important 

 ancestral forms.
