IN the Discussion on Units and Standards, held in the apartments of the Royal Society on March 21, members of the staff of the National Physical Laboratory contributed papers dealing with the measurement of length, mass, the electrical units and temperature. Sir Charles Darwin, director of the Laboratory, in opening the discussion, explained that it would require much more than a single day even to sketch the general field of metrology, and that it had been possible to admit only some of the more important subjects. Time would not be discussed, because this subject is primarily the responsibility of the Astronomer Royal. At the conclusion of the discussion he did, however, touch briefly on some of the derived units not covered by the papers.
