REPORT OF THE SECRETARY. 21 
The preparation of Volume IV of the Annals of the Astrophysical 
Observatory has been in the hands of Dr. Abbot since February; it 
includes the results of measurements from the year 1913. Mr. Fowle 
has continued the work of revising the Smithsonian Physical 
Tables, in which he has received valuable aid from the various 
scientific departments of the Government and from individuals in 
colleges and industrial corporations. 
INTERNATIONAL CATALOGUE OF SCIENTIFIC 
LITEEATURE. 
The United States Regional Bureau of the Catalogue, supported 
by congressional appropriation under the direction of the Smith- 
sonian Institution, undertakes to list and index all scientific articles 
appearing in the United States each year. These titles are for- 
warded to the Central Bureau in London, where they are incorpor- 
ated with the lists from all other countries in a comprehensive cata- 
logue of the year's scientific work of the world. The war and the 
chaotic conditions in Europe since the war, have greatly hampered 
the work of the catalogue and it has been recognized for several years 
that a general reorganization will be necessary when conditions be- 
come more settled. 
The Central Bureau has published during the year 8 volumes of 
the Thirteenth Annual Issue, completing that issue, and 12 of the 
17 volumes of the Fourteenth Issue have appeared. The United 
States Bureau has continued to gather and index the scientific titles 
in this country, and in some of the sciences, notably zoology, the titles 
have been classified far in advance of the published volumes. 
It has been recently announced by the Royal Society of London, 
the principal sponsor of the catalogiie since its inception, that after 
the completion of the Fourteenth Annual Issue a new financial ar- 
rangement will be necessary in order to continue the work, and scien- 
tific establishments and academies throughout the Avorld have been 
asked to offer suggestions as to the best method of accomplishing this 
end. 
NECROLOGY. 
I may here express for myself and on behalf of the staff of the 
Institution and the National Museum the deep sense of loss caused by 
the death during the year of Mr. Richard Rathbun, assistant secre- 
tary in charge of the National Museum, and Mr. A. Howard Clark, 
editor of the Smithsonian Institution. These two men, through 
long connection with the Institution, contributed much to its de- 
velopment and their passing leaves a deep feeling of personal loss 
among their associates.
