Title
[MBLB3168], Letter from Charles Batchelor to John Hopkinson, September 14th, 1883
Editor's Notes
#551 [sent to London] Sorry for not answernig yours from Switzerland. Objected to Sprague's dynamo tests because they were too short. Machines must run all night or up to 16 hours/day. "I find no difficulty in making the armatures give double their former capacity without any change whatever except that of putting sufficient cross sections of wire in them to carry the current without heating. I make a mahcine for 170(?) lamps at a little over the price of the Z, that will run all night with its load on; of course I have a stronger magnet. Haven't yet made new H. Decided to use 1,000 light machines for station here.
