 the study of Alges and Zoophytes, I am anxious to obtain 
 these plants, that may be found in North America in sea as

 that can be collected in North America in sea and sweet 
 water as fresh as possible and instructive (i.e. as far as it 
 is practical with root and fruit) and well dried, of each species,
