Yes. this book is very interesting, with a lot of construction details
that can be useful in "Tesla coiling". The theory parts are interesting
too, to see how these things were treated by that time.

The simplest way to get a page of an old book without damaging it is
by taking a photo (use a digital camera) of it. The image may get a
bit warped, but perfectly readable. I have a program that I wrote
exactly to "unwarp" images of book pages took in this way.
