Abstract
THE International Committee of Weights and Measures at Paris issue from time to time “Travaux et Mémoires” with reference to the investigations and comparisons undertaken at their Bureau during certain periods. Ten such volumes have been published since 1881—Tome i. to Tome xi.—and during last year a further volume, Tome ix., was distributed. This latter volume contains the final account by Dr. J. René Benoit and Dr. Max Thiesen of the comparisons made at the Bureau of forty standard kilograms, “Prototypes nation-aux” with the “Prototype International K,” which is kept at the Bureau. These national standard kilograms have long since been forwarded by the Committee to the Several High Contracting States who (including Great Britain) have joined the Metric Convention of 1875; ard the introductory account of the comparisons of these standards was given in Tome viii. (1893), the final account having only now been issued, although it deals with comparisons made so far back as 1884.
