Read, " Additional observations on the Spongilla fluviatilis." By 

 John Hogg, Esq., M.A., F.L.S. 



The author's views of the vegetable nature of the river sponge 

 were given in a paper read before the Society on the 5th of June, 

 1838, a report of which was inserted in the August number of the 

 ' Annals of Natural History.' 



The present paper contains additional observations in confirmation 

 of these views, derived from a more accurate examination of the 

 seed-like bodies, which are found adhering in abundance to the walls 

 of the cells or cavities of the sponge, and also frequently free and 

 endowed with the faculty of locomotion ; and which have been re- 

 garded by some authors as the ova of the Spongilla, and by others 

 as those of the Plumatella. Mr. Hogg has determined the identity 

 of these bodies, having succeeded in raising young Spongilla from 

 both kinds ; and he has also ascertained that they are destitute of 

 cilia, being merely studded with minute granular papillae. The mo- 

 tions of the unattached bodies resemble those observed by Unger in 

 the sporules of Ectospora clavata, and Mr. Hogg considers the cur- 

 rents to be due to the same causes, which affect the circulation of 

 the fluids in the cells of vegetables.
