Mr. Latona. Counting ridges again, from point No. 5—one, two, three, four. There is a so-called ridge end, which occurs above, above and almost slightly to the left of point No. 5, point No. 5 enveloping No. 1. Point No. 5.
Mr. Dulles. Is 5 a ridge-end?
Mr. Latona. Five is what we term a joining, forking, or bifurcation. These two come together at point 5. Over here, together at point 5.
Mr. Dulles. Is that where the two ridges come together there and encase it?
Mr. Latona. Yes, sir. From point No. 5 we pick up point No. 7, which is another one of those so-called bifurcations. One, two, three, four.
Mr. Eisenberg. Again a ridge count?
Mr. Latona. Ridge counting from 5 to 6. That is in the latent print. We must find the same situation in the inked print. Counting from point No. 5 the ridges which intervene, one, two, three, and then we count four, the point itself. There is the bifurcation right here.
Mr. Eisenberg. Mr. Latona, in making these ridge counts, do you also pay attention to the so-called, let's say, geographical relation, the spatial relation of the two points?
Mr. Latona. Very definitely. Now, it does not always follow that the so-called geographical position will coincide exactly the same. That would be caused because of variations in the pressure used when the print was made. For example, when you make a print on a fingerprint card: when the inked print was made, the print was made for the specific purpose of recording all of the ridge details. When the print was left on the paper bag, it was an incidental impression. The person was not trying to leave a print. In fact, he probably did not even know he left one. So the pressure which is left, or the position of the finger when it made the print, will be a little different. Accordingly the geographical area of the points themselves will not always coincide. But they will be in the general position the same.
Mr. Eisenberg. Mr. Latona, without going into detail, there are some apparent dissimilarities on the two sides of that chart. Can you explain why there should be apparent dissimilarities?
