ing-ly forms tlie basis for the cooperation be- 

 tween the American Society of Zoologists and 

 the Wistar Institute regarding the Journal of 

 Morphology. The full report of the committee 

 •will be published in the proceedings of the 

 1920 meeting of the society, but on account of 

 the general interest the following summary is 

 presented at this time : 



I. That there be elected a managing editor of 

 The Journal of Morphology to serve for a period 

 of five years and that he be eligible for reelection 

 at the expiration of his period of service. 



II. That there be elected nine associate editors 

 of The Journal of Morphology ; three to serve until 

 Jajiuary 1, 1922; three to serve until January 1, 

 1923; and three to serve until January 1, 1924. 



That beginning with the annual meeting of the 

 society at the end of the year 1921, and annually 

 thereafter, there be elected by the society upon 

 nomination, by the same method as is provided 

 for the nomination of other ofScers, three asso- 

 ciate editors to serve for three years to take the 

 places of the three retiring associate editors. 

 That before making nomination of such associate 

 editors, the nominating committee shall consult 

 the board of editors of The Journal of Morphol- 

 ogy and also the director of the Wistar Institute 

 and through him the Board of Advisers of this 

 institute. 



This is suggested as a matter of courtesy to the 

 institute, not as a matter of necessity, for the 

 election of the editors of this journal shall lie 

 with the society. 



That a retiring associate editor shall not be 

 eligible for reelection until after the expiration 

 of one year subsequent to his retirement. 



III. That the three incoming associate editors 

 be constituted a consulting committee to visit the 

 Wistar Institute at its invitation and expense, to 

 serve as a means of cooperation between the two 

 organizations. 



IV. That the board of editors make annual re- 

 port to the society upon The Journal of Morphol- 

 ogy and any matters of publication that they may 

 wish to include. 



V. That the consulting committee, or any of 

 its memibers, if they desire to do so, may report 

 any year to the society any suggestions or recom- 

 mendations growing out of their visit to and con- 

 sultations with the Wistar Institute. 



VI. That Professor C. E. MeClung be elected 

 managing editor of The Journal of Morphology. 



VII. That associate editors be elected as fol- 

 lows: 



1. To serve until January 1, 1922: 



Professor Gary N. Calkins. 

 Professor J. S. Kingsley. 

 Professor WUliam Patton. 



2. To serve until January 1, 1923 : 



Professor E. G. Conklin. 

 Professor M. F. Guyer. 

 Professor W. M. Wheeler. 

 8. To serve until January 1, 1924: 

 Professor C. A. Kofoid. 

 Professor E. E. Lillie. 

 Professor J. T. Patterson. 



VIII. That matters of editorial policy and 

 method, not covered by the present report, be left 

 to the board of editors, subject of course to any 

 action of the society. 



It may be well to state that no fundamental 

 changes in the character or conduct of The 

 Journal of Morphology are contemplated.

A SIMPLIFIED NON-ABSORBING MOUNTING 

 FOR POROUS PORCELAIN ATMOMETERS 



Since the introduction of porous-porcelain 

 atmometers^ into general use among physiol- 

 ogists, ecologists and agricultural experiment- 

 ers, it has been realized that one of the most 

 important details of the operation of these 

 instruments in the open depends upon the 

 fact that the porous, water-imbibed surface 

 absorbs water during rains unless si)ecial pre- 

 cautions are adopted to prevent this. 

 Mounted on a simple tube, as for laboratory- 

 use, these instriunents always give negative 

 readings for periods of rapid precipitation. 

 At the end of a rainy day the reading may be 

 considerably smaller than it should be to rep- 

 resent ruerely the summation of all incre-
