Interesting therefore to compare these ratios with those calculated from the values assigned by the various laboratories to the twelve incandescent lamps of the Bureau of Standards. The ratios calou lated from the incandescent lamp measurements are given in Table IX. In making the computations the intensity of the Carcel lamp.

It would seem that the values obtained through the incandescent lamps are in some ways the more accurate ratios of the units of the various countries, because the primary standard of each country is operated under the usual conditions by the most experienced observers.
