As a result of the deliberation of this 

 Chamber, it was agi'eed to recommend to 

 the several governments rejiresented by the 

 various delegations the adoption of eight 

 units of eleetrieal measure, namely : the 

 ohm, the ampere, the volt, the coulomb, the 

 farad, the joule, the watt and the henry. 

 The Chamber also prescribed definitions 

 for these several units, but as thej- are es- 

 sentially the same as those adopted by 

 Congress, and which ^vill be found in detail 

 below, it is not necessarj' to refer to them 

 here. 



Shortly after the adjournment of the Con- 

 gress a report of its proceedings Avas made 

 to the Secretary of State by the United 

 States delegates, and this report was dis- 

 tributed by the Depai-tment of State among 

 the various nations represented, and also 

 among those not represented, with the re- 

 quest that they should cooperate with the 

 United States in the legalization of the units 

 of electrical measure thus carefullj- selected 

 and defined. In order to secure action on 

 the part of our own Government, a bill was 

 preijared and introduced into the House of 

 Representatives l>y Mr. Charles W. Stone, 

 of Pennsylvania, early in 1894, defining 

 these units substantially in agreement with 

 the definitions adopted by the Chamber of 

 Delegates at Chicago, and declaring them 

 to be the legal units of electrical measure 

 for the whole of the United States. Through 

 the active interest of Mr. Stone, and by the 

 assistance of the American Institute of 

 Electrical Engineers or a few individiuil 

 members tliereof who interested themselves 

 in the passage of the mea.sure, this l)ill be- 

 came a law by the approval of the President 

 on the P-'th of Jul v last.
