ANNALS OF THE ACADEMY 35 
At the summer session the Committee on Weights and 
Measures was authorized and directed ‘“ to communicate with 
individuals and corporations representing the various trades 
throughout the country tendering advice and assistance in any 
efforts they may be disposed to make in regard to the introduc- 
tion of the metric weights and measures.” 
The summer session this year was held in New Haven, 17 
members being in attendance. A singular feature of the scien-

might think proper, while each member was privileged to invite 
a number not to exceed five. The time of the first session was 
by resolution changed from January to the second week in April, 
while that of the second session was changed from summer to

Not content with passing resolutions regarding the use of 
the metric system of weights and measures, the Academy in 
1868 appointed a committee to wait upon the Postmaster-Gen-
