The latter Committee reported on Thursday as iptowa: “ Whereas 
the recent rapid development of the applications electricity 
requires the adoption and legalization of common standards of 
electrical measures to form the basis of contracts for the supply of 
electricity ; and whereas the realization of such standards requires 
that all inetrnments for electrical measures be tested and verified

Conference deems it of national importance that Congress, in pursu- 
ance of its aonasifutloias authority to fix a standard of weights and 
measures, should fix standards of electrical measures, and in order 
to secure the use of said standards should establish a Bureau 
charged with the duty of examining and verifying instruments 
for electrical and other physical measurements. esol ved, That
