CONVENTION NOTES.

The H. W. Johns Manufacturing Company was represented by Mr. W. P. D. Crane from its New York office. In an exhibit held in a corner of the hotel lobby were shown examples of its electrotherm electric heating pads, toggle-clamp feed wire insulator, " H. W. J." electric heaters, its new arc lamp hanger and numerous samples of vulcabeston and moulded mica insulating materials. The electrotherm created much interest on account of its comparative novelty and the satisfactory manner in which the small current utilized maintained the temperature of the pad indefinitely. Special attention was called to the method of regulation by means of a regulating socket and of the insertion in the pads of the thermostat, which prevents the temperature from exceeding the safety limit.
