The test on thepiston-plunger meters was started withNo. 1 and extended thru to No. 6, meters were set in service from1882 to 1891 and at the beginning of testhad been in service from 15 to 23 of these had never been taken o£f. Test was made by variation in tank was placed on a platform scaleand 10 cubic feet, as indicated by the me-ter counter, were drawn into the tank andthen weighed, the proper weight for 10cubic feet being 625 pounds. If the trial. DISC METER opened to show simplicityof mechanism. quantity of water drawn thru the meterweighs more than 625 pounds, the meteris over or in other words it under-regis-ters, and if it weighs less, the meter isshort or over-registers. The result of test on piston meters, asfar as could be ascertained, is as follows: Total of 16S9 meters tested, 108,939pounds over. Total of 1635 meters tested, 41,339pounds short. Total of 107 meters tested, O. K. Total of 80 meters, did not test. 3,511 meters showed difference of 67,600pounds over. Average of pounds over, each, per cent, under-registering. The test of disc meters included thosenumbering from about 6,300 to 14,000, be-ing set from 1891 to 1S95. These metershad been in service about 10 years at thetime of test, most of them never havingbeen retested during that time. The result is as follows: Total of 835 disc meters tested, 9,189pounds over. Total of 952 disc meters tested, 8,474pounds short. Total of
