- Editor's Notes
- We send you by express today the Ampere-meter, which you calibrated for Brown some three months since. # It was returned to us for some slight alteration and repairs, the execution of which has in all probability rendered the original scale inaccurate. # Therefore, we would request that you have it recalibrated for the same ampire(?) capacity, upon an alternating circuit, having not less than 290 alternations per second-- which, we believe, was the rate of alternation of the current used to obtain the original scale. # Kindly return this instrument to us as soon as convenient in order that we may return same to the State Authorities without delay.
