Title
[LB012415A], Letter from Thomas Alva Edison to Francis Robbins Upton, Edison Lamp Co, May 24th, 1882
Editor's Notes
I see in the extract from Defect Book for week ending May 20th 1882 a remark about the water going through the Plaster of Paris and condensing in the Inside Tube. I think this is all moonshine but I should try some experiments by soaking these sockets in water and mix something with the Plaster of Paris say white [wet] that will make them impervious to water. You should answer this Defect Book question
