number of papers were on astronomy, followed by zodlogy, 
physics and geography. 
The Academy this year for the first time voiced its interest 
in scientific activities outside its own sphere by passing resolu- 
tions expressing satisfaction at the action of the Government 
in authorizing the employment of metric weights and measures, 
and recommending that the metric system be taught in the 
public schools, and be made a subject of examination for admis-

considered it highly desirable that the discretionary power 
granted by Congress to the Postmaster-General to use the 
metrical weights in the post-offices be exercised at the earliest

tution to 34 libraries in the United States and 24 in other 
countries. A second number of the Annual was also published. 
The events of 1867 were numerous and important. At the 
opening of the year, in February, the Academy lost its first 
President, Professor Bache. In his report as Vice-President, 
Professor Henry remarked: “ During the past year the Acad- 
emy has been called upon to mourn the loss of its distinguished 
president, Alexander Dallas Bache. This eminent savant de- 
voted his life industriously to the advance of science, and may 
be said to have fallen a martyr to the cause of his country in the 
hour of its peril.” Bache was one of the principal leaders, if
