REPORT OF THE ANNUAL MEETING 
269 
The spectrographic determination of the sun's rotational speeds by comparing the mo" 
tions of approach of the eastern limb and the motions of recession of the western limb with 
the apparent motions of approach or recession of points on the solar meridian passing 
through the earth. The results form a monumental contribution to the complicated and 
still unsolved problem of the solar rotation. 
His long exposures on the spectra of the present-day faint remnants of new stars formerly 
brilliant have shown that these stars are now of the Wolf-Rayet type. 
The more thorough application of high dispersion spectroscopy to the study of the sun's 
chromosphere. Prior to the establishment of the Mount Wilson Solar Observatory, this 
was essentially a total solar eclipse problem. Stratification of the chromosphere has been 
studied by Adams without an eclipse at least as successfully as it had formerly been studied 
at times of total solar eclipse. 
Respectfully submitted, 
W. W. Campbell, Chairman. 
GENERAL BUSINESS 
The following report from the Editorial Board of the Proceedings of the 
National Academy of Sciences was presented by the Chairman, Raymond 
Pearl: 
1. Three volumes of the Proceedings have been completed, and four numbers of the 
fourth volume have been issued. 
The statistics as to the make-up of the third volume, both in respect of subject matter 
and of source of the contributions, have been printed in the Annual Report of the Academy 
for 1917, and need not now be repeated except so far as covers one point. 
The statistics of articles by members of the Academy as compared with articles by non- 
members are interesting mainly in showing a progressive diminution in the percentage of 
articles by members, despite the increase in membership of the Academy. If there are ob- 
stacles which can be removed and which hinder members of the Academy from printing in 
the Proceedings, would it not be well to make efforts to remove them? The Academy repre- 
sents the highest point in American research, and if the Proceedings should actually con- 
tain articles representing the totality of the investigations of members of the Academy it 
would become thereby largely representative of all American research and of very high grade, 
and furthermore it would be more truly the Proceedings of the Academy in the sense that cor- 
responding publications of foreign academies are representative of their research. 
2. At the Autumn meeting the terms of office of five members of the Editorial Board ex- 
pired, and new appointments were made by the Council as follows: Jacques Loeb, W. M. 
Wheeler, E. B. Frost, E. L. Thorndike, and E. H. Moore. 
3. At the Autumn meeting the Board decided to put into operation certain changes in the 
typographical make-up of the Proceedings in the interest of economy. These changes have 
been made with satisfactory results. 
4. The Editorial Board is of the opinion that in view of the now established and recognized 
position of the Proceedings as a medium of scientific publication, the members of the 
Academy might well contribute more of their own papers to its pages than they now do, 
both from the standpoint of self-interest as well as from a sense of duty to the Academy and 
what it stands for. In this connection the Board would recommend that the Academy adopt 
as a general principle the policy of requiring each recipient of a grant for research from any 
of its special funds to publish some account of the results of the researches under the grant 
in the Proceedings. 
5. If the above recommendation is adopted, the Board would further recommend that the 
Acadeny suggest to the several committees having in charge trust funds from which grants 
are made that whenever accounts of researches under grants are published in the Proceed-
