[MBLB4319], Letter from Charles Batchelor to Philip Seubel, July 29th, 1882

Editor's Notes

[consider selecting for the detail it gives on theater lighting, an imporant application we haven't really dealt with yet.] In reply to your letters. Have notified de Mosenthal to write you about safety catch patents. Automatic regulator: haven't seen it yet, but ordered 12 a long time ago. It works on principle of current going through strong magnet of low resistance, which pulls lever to put in resistance (spring takes it back). Munich Exhibition: don't use the waterwheel for power that they offer you (too slow & conmplicated). Theater lighting: I meant stage lighting, the rest is easy. We should lay the wires in Munich, but they want others to do so and also install other lamps alongside ours for night-by-night comparision but this will be trouble. You'll need a number of resistances like those Ross is making for Brunn. I can give you my calcs for this. Discusses regulation of various lights in theater; discusses & illustrates switches being made for Brunn theater. Street lights: 150 cp lamps would be good; will check if any have been ordered.
