_I was highly pleased with the copy of Sloane's Electrical Library,

which arrived in good condition. It is one of the most valuable works

I possess in my library. The use of the Roentgen Rays in my profession

has stimulated my desire for electrical knowledge greatly, and I

consider Sloane's "Electrical Dictionary" a first-class book of

reference. I shall be pleased to recommend it to my colleagues in

search of such a work. Yours truly,_
