Mr. McCLOY. 224 he just begins to appear. Mr. SHANEYFELT. Yes. Mr. McCLOY. I don't think if you assume the President was hit at 225 and I don't think that is clear at all. I think it begins to get clear about 227 that he had been hit, that the reaction really develops. But I think that 225 it may very well be that he has not been hit because his hand isn't at his throat, he may be just moving from the position of waving. Mr. DULLES. But that is about a tenth of a second. Mr. McCLOY. Yes; it is a very short time entirely, but I don't think the frame unequivocally shows the reaction to the bullet at 225. I think it does unequivocally show it at 226 and 227. Mr. SHANEYFELT. That is correct. Mr. SPECTER. Perhaps an additional question on the clarity of the slide itself as a point of reaction would be in order for Mr. Shaneyfelt, and then, may I say parenthetically, we want to have the Commission see these slides this afternoon. We have prepared them to show to you so that you can observe for yourself what we are bringing to you through the witness to give you a frame of reference and an orientation. Mr. Shaneyfelt, then what was your impression by frame 225, as you viewed it most recently this morning, with respect to a possible reaction on that frame made from the original Zapruder film? Mr. SHANEYFELT. It is my feeling that at frames 225, 226 and 227 you are having a reaction. You have a split second there, and at 225 the reaction is barely discernible, more discernible on the film and the slides than the reproduction you have here but it has to be considered in the light of the motion picture you see as he starts this reaction, and the reaction is by frame--in either the slides or pictures--is clearly apparent in 226, and barely apparent in 225. Mr. SPECTER. Now, was frame 249 selected as a situs for calculations on the possible construction that President Kennedy was struck in the back at the first point unadjusted at which he emerged from the tree, to wit: frame 207, with an additional calculation of 42 frames giving the approximately two and a quarter seconds for the firing of a second shot to determine through this one means whether there was time for the rifleman to have operated the bolt, assuming he made a shot at 207, and to have made another shot at the earliest possible time at 249. Mr. SHANEYFELT. That was the basis for the selection of frame 249, yes. Mr. SPECTER. Now, going back just a moment, was frame 231 selected as a basis for analysis as the first frame after 225 because Governor Connally expressed the opinion when he viewed the frames that he thought he was hit by or at frame 231. Mr. SHANEYFELT. That is correct.
