plant to that celebrated Society, that at least one fact might be 

 established, viz. that this plant had never been sessile. Now 

 although this point was very easy to decide on the specimen 

 sent, yet a learned member of the Academy, evidently without 

 examining the specimen, supposes nevertheless that it may 

 have been torn loose. 



After the establishment of this fact, that the floating perfect 

 fuci in the Sargazzo sea have not been sessile, we arrive at 

 the question, whence then have the seeds of this plant come ? 

 But this question also is not difficult to answer if we consider 

 the powerful currents which prevail in and about this sea, 

 especially as we know that the sessile specimens of the Sar- 

 gassum natans on the American coast, and probably on the 

 coasts of the Azores, &c., bear fruit.
