a2, ANNUAL REPORT SMITHSONIAN INSTITUTION, 1914, 
In 1852 the Institution published the first edition of the Smithsonian 
meteorological tables, which were so widely used by physicists during 
the next 40 years that it was decided to publish three sets of tables, 
independent of one another, but forming a homogenous series. The 
first of the new series, Smithsonian Meterological Tables, was pub- 
lished in 1898; revised editions were issued in 1896, 1897, and 1907, 
and another revised edition is now under consideration. The second 
series, Smithsonian Geographical Tables, appeared in 1894, editions 
slightly revised were issued in 1897 and 1906, and additional copies 
of the last edition were printed during the past year to meet the 
constant demand for this work. In 1896 there was published the 
Smithsonian Physical Tables, which have passed through several 
editions, the sixth revised edition being now in press. In this latest 
edition are incorporated many new tables and the insertion of recent 
data in the older tables to conform with the great advances in various 
fields of physical science. A fourth series is the Smithsonian Mathe- 
matical Tables (Hyperbolic Functions), published in 1909. 
Smithsonian Report.—The distribution of the Annual Report for 
1912 was long delayed, awaiting a supply of the quality of paper 
used in that publication. The volume contains 38 articles of the 
usual character in the general appendix. The report for 1913 was in 
type at the close of the fiscal year. The popularity of this publica- 
tion continues unabated, the entire edition each year becoming ~ 
exhausted very soon after its completion. 
Special publications—F or several years past the Institution has 
issued in printed form the Opinions rendered by the International 
Commission on Zoological Nomenclature. During the past year 
Opinions 57 to 65 were thus published. To aid the work of this 
commission the Institution also provides for clerical services in con- 
nection with the oflice of its secretary in this country. 
Another special publication of the year, printed in a limited edi- 
tion, was a pamphlet giving an account of the exercises in the Smith- 
sonian building on May 6, 1913, on the occasion of the presentation 
of the Langley medal to Monsieur Eiffel and to Mr. Glenn H. Curtiss, 
and the unveiling of the Langley memorial tablet. 
Harriman Alaska Series —In 1910 there was transferred to the 
Smithsonian Institution by Mrs. Edward H. Harriman the re- 
mainder of the edition of volumes 1 to 5 and 8 to 13 of the elaborate 
publication on the results of the Harriman Alaska Expedition of 
1899. It may be recalled that this expedition was organized with 
the cooperation of the Washington Academy of Sciences, but entirely 
at the expense of the late Mr. Edward H. Harriman, of New York. 
Tt was participated in by a large party of scientific specialists, on a 
steamship specially chartered for the purpose. A narrative of the 
irip and observations on the regions visited, together with desecrip-
