characters of that constituting an Ama^ba. By the side 

 of these there are other masses without any apparent 

 membranous envelope, whose substance is similarly 

 glutinous and granulated • whilst elsewhere other

globules are found, whose development is undoubtedly 

 less advanced, showing a less refractive substance 

 and an irregular granulation which appears more on the

glutinous matter increases as the cell becomes older^ and 

 its different states necessarily indicate a slow modifica- 

 tion of the nutritive juices of the plant — a modification 

 which tends in a manner to animalize it, since from 

 this very matter there arises, as we 

 multitude of Infusorial animalcules. ... In their course 

 from one extremity to the other of the cell, the different

 and form upon different parts of it an irregular layer, 

 which is transparent and more or less mammellated. It 

 is then that the Infusoria make their appearance: 

 Monads, Amcrb^, Keronse, VorticelliE, Actinophrys, 

 Rotifers, all appear, all show themselves successively 

 whilst passing through different stages of development, 

 and in from fifteen to twenty-one days the vessel is
