international conferences were held in Paris to consider the 
question of preparing new metric standards, one in 1870 and the 
second in 1872. In this connection a proposition was put for- 
ward for the establishment of an international bureau of weights 
and measures, and the matter was submitted to various govern- 
ments including that of the United States for consideration. It 
was brought by the Secretary of the Treasury on March 7, 1873, 
to the attention of the Academy which in turn referred it to the 
Committee on Weights and Measures. On June 13 of that year 
a report was transmitted to the Treasury Department. 
Two years later, in 1875, the metric convention at Paris voted 
for the establishment of an international metric bureau and in 
April of that year, as was noted in an earlier chapter, the 
Academy adopted resolutions proclaiming its belief in the use- 
fulness of such a bureau, and its “solicitude that the Govern- 
ment of the United States should ratify the convention prepared 
to that effect.” A copy of the resolutions was transmitted to 
the President, with a request for his favorable consideration. 
This letter was as follows: ”
