This zip has all of my copies of figures 6-8; I digitized each photo, sometimes
several times at different resolutions.  As I am a naive digitizer and
photohacker, there may be some artifacts introduced into these.  One of each of
these is the original digitization so you can see what I worked with (tho I've
lost track of which is the original).

Figure 6: the horse photo
    clever-h.jpg
    clever-h.tif
    hans.tif
    hans2.tif

Figure 7: Rana
    rana.jpg
    rana.tif
    rana000.tif
    rana2.tif

Figure 8: Grande
    page144.jpg
    grande.tif


In Figure 8, page144.jpg is longer than grande.tif.  I clipped some of the
middle out of page144.jpg in order to get it to fit on the page better.
