Mr. Barnes. Since 1956.
Mr. Belin. Roughly, how many of those do you do in a month on an average?
Mr. Barnes. It would be hard to say. If I hit it lucky, I won't make too many. If it hits on some other man's duty. It would be hard to say how many I have made over a period of time. I can say that I have made many.
Mr. Belin. Over these years, do you think you have made as many as 100?
Mr. Barnes. It would be hard to say. I am not going to go into any actual figures because it would be guesswork.
Mr. Belin. Well, let me ask you this. Of the paraffin tests that you have made, how many have you made of a cheek or cheeks?
Mr. Barnes. One.
Mr. Belin. Was that with Lee Harvey Oswald?
Mr. Barnes. It was.
Mr. Belin. Other than that, you have never made a paraffin test of anyone's cheek?
