Mr. Eisenberg.

And do I understand that if that had happened, the person would have left evidence behind which you would have detected?

Mr. Cadigan.

In my opinion, yes.

Mr. Eisenberg.

And that would be in what form?

Mr. Cadigan.

It would be in, many forms. Failure to incorporate into the writings things that should be there, and including in the writings things that are not in Oswald's writing, differences in slant, spacing, proportions of letters, both to other letters and proportions of letters within themselves, the adoption of the various variations that you find in the known writings. When the amount of writing approaches the amount involved here, there is a large, a relatively large volume of questioned writings. The possibilities of successful or undetectable forgery, in my opinion, are nil.

Mr. Eisenberg.

Mr. Cadigan, I now hand you Commission Exhibit No. 1, which is a note in the Russian language in cyrillic print, and ask you whether you have examined that item?

Mr. Cadigan.

Yes.

Mr. Eisenberg.

I now hand you Commission Exhibit Nos. 55, 56, and 66, consisting of various notes in the cyrillic language, rather in the Russian language in cyrillic print, and ask you whether you have examined those notes?

Mr. Cadigan.

Yes.

Mr. Eisenberg.

Who is the purported signer of those notes, Exhibits Nos. 55, 56, and 66?

Mr. Cadigan.

From the translation that I read these are purportedly written by Lee Harvey Oswald.

Mr. Eisenberg.

Now, for the record, these have also been identified by Marina as having been written by Lee Harvey Oswald.
And these are signed Alek in some or all cases?

Mr. Cadigan.

Yes; they are signed A-l-e-k, Alek in all three instances.

Mr. Eisenberg.

Again, for the record, this is a name which was used for Oswald during his period of staying in the Soviet Union.
Have you attempted to determine whether Commission Exhibit No. I was written by the person who wrote Commission Exhibits Nos. 55, 56, and 66?

Mr. Cadigan.

Yes.

Mr. Eisenberg.

And what was your conclusion?

Mr. Cadigan.

That Commission Exhibit No. I was written by Lee Harvey Oswald.

Mr. Eisenberg.

Have you prepared photographs of Commission Exhibits Nos. 55, 56, and 66?

Mr. Cadigan.

Yes; of the letters contained in those exhibits.

Mr. Eisenberg.

I will mark those as Cadigan Exhibits Nos. 25, 26, 27, and 28.
(The documents referred to were marked Cadigan Exhibits Nos. 25, 26, 27, and 28.)

Mr. Eisenberg.

Have you also taken a photograph of Commission Exhibit No 1?

Mr. Cadigan.

Yes.

Mr. Eisenberg.

I will mark that as Cadigan Exhibit No. 29----

Mr. Cadigan.

Front and back.

Mr. Eisenberg.

And Cadigan Exhibit No. 30, representing respectively the back and front of Commission Exhibit No. 1.
(The documents referred to were marked Cadigan Exhibits Nos. 29 and 30.)

Mr. Eisenberg.

Now, by use of photographs Cadigan Exhibits Nos. 25 through 30, could you explain some of the reasons which led you to your conclusion?

Mr. Cadigan.

Yes; and I would point out that in addition to the four enlargements written in Russian, I also used Cadigan Exhibits or the documents represented by Cadigan Exhibits Nos. 4 through 10, the known standards of Oswald, since there are English letters interspersed with the Russian writing on Commission Exhibit No. 1. Thus, for example, in the second line in Cadigan Exhibit No. 29 appears the word "to" which is directly comparable to the
