My Dear Sir — I desire to acknowledge, on behalf of the Colorado 

 Scientific Society, your very kind invitation to send a delegate to Law- 

 rence to represent our Society in the semicentennial anniversary of the 

 Kansas Academy of Science. If it is at all possible for me to do this I

IOWA ACAD.EMY of SCIENCE. 



Represented by Prof. J. E. Todd, A. M., University of Kansas, LawTence. 



To the Members of the Kansas Academy of Science: 



I come to your semicentennial celebration as delegate from the Iowa 

 Academy of Science, of which I was a charter member and for many 

 years a corresponding member. 



I bring you the hearty congratulations of your sister society. Our 

 two societies have several things in common. Some of our former mem- 

 bers have from time to time become identified with you, as Doctors Patrick 

 and Haworth, and others. We are both in the Middle West, both in lead- 

 ing agricultural states with important mines in coal and lead with some 

 gypsum. We can therefore appi'eciate more fully and value more ac- 

 curately the scientific zeal, wisdom and efficiency indicated by the fact 

 that you, in a considerably younger state, are preceding us by several 

 years in celebrating your jubilee year. 



We therefore cheerfully recognize this preeminence on your part, and 

 will count ourselves fortunate if en our fiftieth year we find our pub- 

 lished proceedings as varied and practical and our work as fully appre- 

 ciated and supported by the state. 



We congratulate you most sincerely.
