4 PLANTS OF MASSACHUSETTS. 



It was my intention to make some report on the cellular plants, — 

 the cryptogamous vegetables, — but there has not been time to ac- 

 complish it. 



It is not to be expected that the Report is entirely perfect, but care 

 and effort have been employed to make it as complete as possible. 

 With high respect and consideration, 



I am your Excellency's 



Very obedient servant, 



C. DEWEY.
