Mr. DULLES. I did not get the two. I get the two ridges coming together with sort of the ending of a valley. You were saying there were two distinctive things. I have only caught so far one distinctive thing--that is the two ridges coming together in a kind of valley with no exit. Mr. LATONA. Two that come together, like a fork. And the other one was the one that just ends by itself--does not join. Mr. EISENBERG. Which is an interrupted ridge? Mr. DULLES. I do not get the distinction. Mr. EISENBERG. Is that an interrupted ridge you just described? Mr. LATONA. What we call an ending ridge. Mr. EISENBERG. Off the record. (Discussion off the record.) Mr. EISENBERG. Back on the record. Mr. Latona, could you prepare a diagram which would show some of the characteristics, in broad outline, which we have been discussing, and have those labeled, and could you submit that diagram to us at a future date? Mr. LATONA. Yes; I could. Mr. EISENBERG. We will append it to your testimony, so that your testimony may be more easily followed in the record--with the permission of the Chairman. Representative FORD. It will be prepared and submitted and included in the record. (The item referred to was later supplied and was marked Commission Exhibit No. 634A.) Mr. LATONA. Well, if you could give me your indulgence, I could do it right here as fast as I did it on the board. Representative FORD. Off the record. (Discussion off the record.) Representative FORD. Back on the record. Mr. DULLES. These, I understand, are the particular distinguishing points, the points that you would look for to determine whether the latent print---- Mr. LATONA. Not so much the looking for the points, as to finding points having a relationship to each other. It is the relation that is the important thing, not the point itself. In other words, all of us would have to a certain extent these points. Mr. DULLES. They have to be in the same relation to each other. Mr. LATONA. That is correct. For example, on the illustration I have here---- Mr. EISENBERG. This is an illustration on the blackboard. Mr. LATONA. The mere fact that this is an ending ridge and bifurcation and another ending ridge and a dot in themselves mean nothing. This is a type of pattern which is referred to as a loop, which is very common. These comprise approximately 65 percent of pattern types. It has four ridge counts, for example. You can find hundreds of thousands and millions of four-count loops. But you would not find but one loop having an arrangement of these characteristics in the relation that they have. For example, the enclosure is related to this ending ridge. This ending ridge is related by one ridge removed from the dot. This bifurcation is next to the so-called core which is formed by a rod, the ending ridge. The points themselves are common. The most common type of points are the ending ridge and the bifurcation. Those are the two points we have covered so far.
