disease. From the analysis, however, it is not difficult for the 
medical practitioner to ascertain whether a given water will 
probably be useful in a certain specific case. 
Although this report contains analyses made by the author 
as early as 1883, and from that time to the present, yet it is 
only since 1896 that any special attention has been directed to 
the systematic analysis of the mineral waters of the state. The 
more important localities have been personally visited, and sam- 
ples of water have been secured, and, at the same time, special 
observations have been made upon temperature, flow, situation, 
dissolved gases, etc., which could be made only at the original 
source of the water. 
There are included in the list of analyses, however, quite a 
large number of waters that have been analyzed at the State 
Agricultural College, at Manhattan, by Prof. G. H. Failyer and . 
his assistants, reports of which have been published in various 
scientific periodicals. Other analyses, as reported by chemists 
outside the state, are also quoted. The department is also in- 
debted to Dr. E. B. Knerr, of Midland College, Atchison, for 
his constant interest in the work, and for furnishing analyses 
of the waters in the vicinity of Baxter Springs, Atchison, and 
from Brown county. 
Several of the faculty of the Chemistry Department, especially 
Prof. E. C. Franklin, Prof. H. P. Cady, Mr. D. F. McFarland, 
and some advanced students of the University, have contributed 
not a little to the facts here recorded. ‘The analyses are, as far 
as possible, credited to the proper persons. 
It has been the object of the department to thus collect and 
preserve in a permanent form, for the benefit of the citizens of 
_ the state, as much reliable material as possible on the mineral 
waters. It has not been thought to be advisable to include in 
. this volume the very closely related subject of the potable wa- 
ters of the state, city supplies, and those used for domestic sup- 
ply; so the investigation of the rivers and streams has been 
left for a later and more extended research. 
It is not possible in a limited time to describe and since all 
the so-called mineral waters of the state, and it is quite probable
