those which were supposed to be all right. There were but few 

 analyses of waters away from Lawrence, owing to the difficulty 

 of obtaining samples. Through the kindness of Prof. E. C. 

 Murphy, a number of samples were obtained from the Neosho, 

 the Verdigris, and the Marais des Cygnes. The comparison of 

 these with the waters of the Kansas is quite interesting. It 

 would be still more interesting, however, if the analyses of the 

 river waters could be made more frequently, and at different 

 stages of the rivers. 



The methods of analysis are those in use in the laboratory of 

 the state board of health of Massachusetts. Analyses have 

 usually been made on the day following the date of collection, 

 or within twenty-four hours from the time the water was ob- 

 tained. The records are given in parts per million, according 

 to the recommendation of the American Chemical Society. 



We realize that the work has been merely begun, and that but 

 little has been done, due partly to the lack of a well-equipped 

 water-analysis laboratory, and partly to the fact that the stu- 

 dents who assisted in the work were carrying on the regular 

 university courses at the same time. Nearly 250 analyses have 

 been made, the reports of which are arranged in the twelve ta- 

 bles of this report.
