Looking at the immense advance made in the field of chemistry, it is interesting to notice some of the contributions to this science in Kansas, and especially what has been done in the fifty years of the life of the Academy. was and is preeminently an agricultural state, and for years little was done in applied chemistry. To the colleges, such as the University of Kansas, the State Agricultural Emporia Normal, Washburn, Baker, Southwestern, Ottawa, McPherson and others, and to the larger high schools, was left most of the work of instructing in chemistry. All these institutions at a very early period in their history offered elementary courses in chemistry, which were soon extended to include qualitative and quantitative analysis. In the more recent years organic chemistry and physical chemistry, as well as many special courses, have been added to the curriculum in these schools. instruction given in the various schools led to sending out a large number of scientific men and women, who have made their mark in chemistry and allied subjects. Many well-equipped men have been sent to the various departments of the national government and to state experiment stations. In addition to the work of instructing in chemistry, these institutions have found time to carry on research work. As an illustration, note the extent to which the Transactions of the Academy of Science has been used as a means of publication of papers on chemistry. first chemistry paper was by W. H. Saunders, the first professor of chemistry in the University, on the Comparison of Coals with Other Western Coals. Up to the year 1900 chemical papers were published as follows: By E. H. S. Bailey, twenty-five; L. E. Sayre, sixteen; J. T. Willard, eleven; G. H. Failyer, eleven; George E. Patrick, eight. That is, a total of about eighty papers of an essentially chemical nature were contributed during this period by the above men and others associated with them. That these papers had a very practical bearing on the economic development of the state is apparent from a glance at some of the titles, such as Kansas Chalk, The Iola Gas Well, The Waconda Meteorite, Ozone in Atmosphere, Ammonia and Nitric Acid in Rain Waters Collected at Agricultural College, Some Mineral Waters, Chemical Composition of Coals, The Newly Discovered Salt Beds in Ellsworth County, Chemical Composition of Cement Plaster, Effect of Continuous Cropping of Wheat on the Composition of the Soil, The Sugars of Watermelons, Variations in the Nitrogen Content of Maize and Possibilities for its Improvement. There is no necessity for going into details regarding advancement in chemistry during the last few years, since most of those present are familiar in a general way with the progress that has been made. However, it would not do to let the opportunity pass without calling atten-
