[D8534E], Letter from William Henry Preece to Thomas Alva Edison, March 17th, 1885

Editor's Notes

I sent you the Woodhouse and Rawson lamps that you asked me to order. The Edison Co. here, represented by Major Hood Page, have declined to allow any competitive tests to be made either of your lamp or Swan's, claiming that any such experiment carried out publicly might affect the legal questions now pending. There is no doubt that the value of your patent right in the incandescent filament is of far greater value to you than any scientific contest, so I have reluctantly acquiesced in the veto that has been put on the anticipated trial. I wish, however, that you would let me have a few of your latest form of 50-volt lamps--your "B" lamps--so I can fix them up in my own house and compare their behavior with Swan's and Woodhouse and Rawson's, and a few others that I have. This is for my private guidance only and not for publication. ##The question of holders is very awkward, for every man uses his own holder. If you could make me these lamps with loops, they would give me less trouble than if you supplied me with your form of holder. I think your holder is the best and I am sorry that it has been departed from, "but in this as in everything else every man thinks his the best and will have his own way." ##I have been making an interesting set of experiments with the lamps you sent me. I hope to have the resutls before long. ##Our Inventions Exhibition is going to be a very successful one and I sincerely hope you will carry out your intention of coming over to England this year.
