When we pertain to the topic of the
economic situation of the Nernst lampquite an array of diverse opinion is presented. Drude, the distin-guished German physicist, debts the Nernst glower with an absoluteluminous efficiency of 12 each cent., the equivalent efficiency of theincandescent lamp filament being variously specified by authoritiesat from 2.5 per cent, to 6.5 per cent.: on the other hand, the claimhas been made by an incandescent lamp interest that the efficiencyof the Nernst lamp in industrial service is virtually the sameas that of the average incandescent lamp. If, nonetheless, we accept Tumlirzs constant of 5.2 for the number of candles per watt for aluminous efficiency of 100 percent, a 3.1-watt incandescent lamphas a luminous efficienty of 6.5 percent, as well as a Nernst glower of 12per cent, luminescent efficiency represents an usage of 1.62 watts each cp.When one refers to the candle light power e.xperiments that have been Text Showing up After Image: FIG. 10.– TESTING B. LLASTS. made on the commercial Nernst lamp, the outcomes fit to be socontingent on the experimenters analysis of just what constitutesa candle light power– whether it is to be taken into consideration in a spherical, hemis-pherical or some other importance– that the data are of little valuefor relative objectives. It happens, however, that the Photo-metric Committee of the National Electrical Light Association hasreported on dimensions of the Nernst light in such a kind that acomparison could be made between the efficiency of this light andthat of arc lamps examined by the exact same committee and presurqably ac-cording to the same approaches. According to this record, the wattsper hemispherical candle light power eaten by a six-glower lampwere 1.88 each cp. with clear world as contrasted with the followingenclosed arcs with opal inner globes and also clear outer globes: Direct-current series, 1.3 watts; direct-current several, 2.25 watts; alter-nating-current series, 1.19 watts; alternating-cur Note About Images Please note that these photos are drawn out from scanned page photos that may have been electronically boosted for readability- coloration and look of these pictures may not perfectly resemble the initial work.

Huge Rocks. Although our state is kept in mind for the fantastic abundance of bouldersstrewn over its surface, it is only rather just recently that I have actually seen boul-ders in our limitations bigger than any one of which mention has been made inthe works of American geologists. They were brought to our noticeby His Excellency Guv Prescott. Regret had actually been revealed tohim that no boulder had actually been located in the state equal in size to thoseknown to exist in the nearby states.
