PROCEEDINGS OF THE 
Twenty- Second Annual Session of the 
Iowa Academy of Science 
The meetings of the twenty-second annual session of the Iowa Academy of 
Science were held in the Chemical Lecture room at the Iowa State Normal 
School, Cedar Rapids, on May 1 and 2, 1908. 
In the business meetings the following matters of general interest were 
presented :

To the Members of the Iowa Academy of Science. 
The twenty-first annual meeting of the Academy was held at Drake University, 
Des Moines, on Friday and Saturday, April 26 and 27, 1907. The meeting was 
well attended. When called to order on Friday afternoon nineteen members 
were present. The papers presented at the meeting were interesting and

meeting. 
The membership list is undergoing a revision that the committee is attempt-

Proceedings that will be stricken out in accordance with the requirements of the 
by-laws. At the last meeting four new names were proposed for fellows, two 
were transferred to the corresponding members list, and fourteen names were 
proposed as associate members. These names were all acted upon favorably by 
the council. By some error, the addresses of most of those proposed as members 
did not reach the secretary and correspondence with the fellows of the Academy 
failed to obtain the desired information with reference to eight of the number. 
A repetition of siich an error is not probable. 
The publication of the Proceedings has been delayed even more than it was 
last year. The meeting of the Academy was held in April; the last paper for 
publication was not received by the secretary until in August, although the 
endeavor was made to collect them early after the meeting. The Executive 
Council of the State is very careful concerning the ordering of State printing. 
A delay was caused by the Council awaiting a decision of the Attorney-General 
with reference to its powers in relation to the publication. Another delay was
