I Original references for Hertz's experiments

[qnach]

There are many website about the apparatus of Hertz's experiments, i.e.
http://www.sparkmuseum.com/BOOK_HERTZ.HTM
http://earlyradiohistory.us/1901hz.htm
http://people.seas.harvard.edu/~jones/cscie129/nu_lectures/lecture6/hertz/Hertz_exp.html

There are many pictures showing the apparatus of Hertz's experiments. But I cannot find the original references where those pictures came from. Could anyone provide me the original references. Thanks.

In that last link, below the pictures there is a link indicated as (source). If you click that link, you will find the same pictures, with the note

Figure 1 diagrams adapted from "Electric Waves", by Heinrich Hertz,MacMillan &Co. (1900)

So I guess the pictures come from Hertz's book.

I want the source of the first two pictures of the link you mentioned.
But those two pictures has no "source", and the source you mentioned do not contained those pictures.

Which book of Hertz do you mean? I checked some...but find none.

Looking at those pictures, I would think they are not original. No idea where they could come from.

As for the book, it is Electric Waves, and it appears to be available at https://archive.org/details/b2172457x

The book is in English. Hertz is a Germany.
