Hi Tuppence,
back again?
Which of those books did use Haeckel's embryonic sketches and which didn't? Let's look at the first example:
Alton Biggs, Chris Kapicka, and Linda Lundgren, Biology: The Dynamics of Life (Westerville, OH: Glencoe/McGraw-Hill, 1998). ISBN 0-02-825431-7
According to this review (pdf):
“The embryos of a fish, a reptile, a bird, and a mammal are shown in Figure 15.9. At this stage of development, all the embryos have a tail and
pharyngeal pouches. In fish, these pouches develop into the supports for the gills, while in mammals, reptiles, and birds, they develop into parts of ears, jaws, and throat."
Now compare this to ApostateApe:

The only similarity embryonic x-ray images have to Haeckel's sketches are tails, and they don't look anything like what Haeckel drew. If you are going to criticize my argument, then criticize my argument and not a barely-related straw man.
The figure isn't shown, but I doubt you will see Hackel's drawing. Maybe a redrawn version, but this can mean almost everything. Did you check your source?
