:55:01
Just like what I've done
every time.

:55:02
Then I placed it
in the electrometer.

:55:08
And I close the case
so there is no draft.

:55:10
Good.
:55:11
I charged the electrometer.
:55:19
Now I will find out
how much energy to raise

:55:21
in the pitch blende they have
is it right?

:55:22
Right. Start.
:55:25
Ready. Read.
:55:39
Eight.
:55:41
Eight.
:55:41
Same reading as I always had.
:55:44
This pitch blende
with the uranium and the thorium

:55:46
still in it comes to eight.
:55:48
Now, here is pure uranium
:55:50
I strike it
in the same amount of pitch blende.

:55:52
This is exactly the same case
close the case

:55:55
charged the electrometer
:55:57
Now, we will find out
:55:58
how much energy
the rays in the uranium have.

:56:00
Right.
:56:02
Ready. Read.
:56:12
Two, same as always.
Done nothing wrong so far.

:56:16
Not that I can see.
:56:18
We know then that...
:56:19
the pitch blende with
the uranium and thorium in it

:56:21
comes to eight and that
the uranium alone reads two.

:56:25
I am going to test the thorium.
:56:26
From the same amount of pitch blende?
:56:27
Of course, and put in exactly
the same case

:56:29
close the case
charged the electrometer.

:56:32
Now we find out how much energy
the rays in thorium have?

:56:34
Right.
:56:36
Ready. Read.
:56:44
Two
:56:50
I don't understand.
There must be a mistake.

:56:55
When the uranium and thoarum are
in the pitch blende

:56:57
the reading is eight.
:56:59
But individually
they only total four.
