Mr. Hogg therefore maintains it to be impossible to account the 

 Spongilla as belonging to the vegetable kingdom and the Spongia 

 to the animal ; and since he has become sure of the former, and since 

 the Spongia is now known to possess neither one organ nor a single 

 property peculiar to an animal, he has been at length forced to ac- 

 knowledge the vegetable nature of the Spongia. 



Moreover, the fact of Dr. Grant having witnessed the locomotive 

 sporules of some of the sea sponges germinating and developing 

 themselves after the forms of their parent structures, at once decides 

 that they cannot be the nidus or matrix, or the fabrication or produc- 

 tion of any marine animal. 



Lastly, Mr. Hogg, considering to what order of plants the fresh- 

 water and the sea sponges should be referred, proposed to classify 

 them in a separate order " Spongiae," which ought to be placed 

 between the orders Fungi and Algae.
