Is there anything, Mr. McKenzie, you would like to know about our procedure that you are not acquainted with? It is very informal.

Mr. McKenzie. Mr. Chief Justice, I will say this. This is the first time I have had the privilege of appearing before such a distinguished group of citizens of this country, headed by yourself, and that we are ready to proceed.

The Chairman. Mr. Jenner?

Mr. Jenner. Thank you, Mr. Chief Justice.

May I suggest the wisdom of identifying each of these series of four letters with an exhibit number, and may the reporter supply me with the next number.

The first letter mentioned by Mr. McKenzie is the letter dated February 17, 1964, addressed to Mr. McKenzie, and signed by Mr. Robert L. Oswald, witnessed by Mr. Henry Baer, Joan Connelly, and Peter White. That will be marked Commission Exhibit No. 272.

Mr. Jenner. The second letter mentioned by Mr. McKenzie is dated February 18, 1964, also addressed to Mr. McKenzie, signed by Mrs. Marina N. Oswald, and witnessed by Declan P. Ford, Katherine N. Ford, and Joan Connelly. That will be marked Commission Exhibit 273.
