The door is open, show-ing the construction and manner of operation. The novel features and improvements to this new voltmeterare: First, it is equally applicable to both alternating or directcircuit; second, it recjuires only one-third as much current tooperate as that necessary for the older design for alternatingcurrents; third, it is more sensitive to very slight variations of SEMI-CONVERTIBLE CARS FOR SOUTH A shipment of cars of the interesting type illustrated haslately been maile to the Cape Government Tramways, CapeTown, South y\frica, by the J. G. Brill Company. The carsare divided into three compartments, the first-class one being6 ft. 9j4 ins. long and seated for seven passengers, the third-class being 3 ft. ()% ins. long and seated for four passengers,and the compartment in the center for luggage, 3 ft. 6% cars have the builders semi-convertible window system.
