The well is 80 feet deep. The owner of the well states, that at a depth of about 60 

 feet a blowing noise was heard in the well, as though a cavity containing compressed gas 

 had been tapped. He does not remember to have observed the odor of hydrogen sul- 

 phide at this time. The noise may have been due to the escape of this gas, but it does 

 not seem probable. 



In giving the analytical results, I have preferred to give the substances found, with- 

 out combining them. Except in those cases where the compound may be precipitated 

 by boiling, as in the case of the carbonates, only a shrewd guess can be made regarding 

 the combination of the bases and the acids in such complex and dilute solutions.

 properly belonging to the proceedings of this meeting. It appears as received by Professor W. A. 

 Kellernian, at whose request it was written. — Secretary.] 



A CONTRIBUTION TO THE FLOEA OF KANSAS — GRAMINEAL. 



( With Plates I, II and III.) 



BY F. LAMSON SCRIBNER. 



To Prof. W. A. Kellermax: I have examined the Kansas grasses contained in the 

 package recently received from you, and I present herewith my determinations of the 

 species. They are for the most part widely distributed in this country, and all save two 

 of the genera — Chloris and Munroa — are described in Gray's Manual. Nearly double 

 the number of species of grasses here enumerated probably occur within the limits of 

 your State. The list is arranged according to the classification in Bentham and Hooker's 

 Genera Plantarum.
