Beginning with Volume XI the Davenport Academy of 

 Sciences will change the manner of publication of its Pro- 

 ceedings. To avoid the delay incident to waiting for vol- 

 umes to be completed, and to make less likely the burying 

 of valuable papers in a general volume, hereafter the separate 

 papers will be distributed in pamphlet form as soon as printed. 

 The last section of each volume will contain reports of officers 

 and a record of the Academv meetino^s, tosfether with title 

 page for the volume, table of contents, and index. This plan 

 will make possible the binding of the volumes of the Pro- 

 ceedings by those libraries and societies that wish to keep 

 their file intact. On the other hand there will be a more 

 prompt and direct distribution of the separate papers to those 

 who are most interested.
