IOWA ACADEMY OF SCIENCES 
The State Printer has been eminently fair and obliging in connec- 
tion with the Academy work, and I am glad to testify to the improve- 
ment in this regard since a few years ago. 
The Executive Council very courteously allowed all the plates that 
were requested for the last voume of the Proceedings. However they 
especially requested that in the future there should be submitted with 
each drawing or photograph, from which a plate is to be made, a short 
description stating what such drawing or photograph represents, and 
the reason why it is desirable that the same should be used as an illus- 
tration in addition to the description of the same tacts in the text. 
Since the members of the Executive Council are not scientists, and 
since the Secretary cannot have such a knowledge of every branch of 
science as to enable him to present the descriptions and claims for each 
illustration as well as can the party who submits the same, I think the 
request should be endorsed by the Academy.

year, there is presented below a list of the periodicals and books that
