NOTE. 



It has been thought well to attach to the foregoing, in the form of an 

 appendix, a report of Mr. Clifford Richardson, formerly Assistant 

 Chemist of the Department of Agriculture, on the Chemical Composi- 

 tion of American Grasses, from investigations made by him in the 

 laboratory of the Department of Agriculture, 1878-1882. 



The appendix also includes, for the benefit of those readers who may 

 wish to familiarize themselves with them, a glossary of the botanical 

 terms used in describing grasses.
