Section 4.5 says:

   reassembled original packet:

   +---------------+-----------------+---------+--------+-//--+--------+
   | Per-Fragment  |Ext & Upper-Layer|  first  | second |     | last   |
   |    Headers    |     Headers     |frag data|fragment|.....|fragment|
   +---------------+-----------------+---------+--------+-//--+--------+

It should say:

   reassembled original packet:

   +---------------+-----------------+---------+--------+-//--+--------+
   | Per-Fragment  |Ext & Upper-Layer|  first  | second |     | last   |
   |    Headers    |     Headers     | fragment|fragment|.....|fragment|
   +---------------+-----------------+---------+--------+-//--+--------+

Notes:

The figure in the "original text" is inconsistent with an earlier figure of the "original packet" (in page 18), where the "Ext & Upper-Layer Headers" part is followed by "first fragment" (rather than "first fragment data").

As an alternative to the "corrected text" above, one could modify such earlier figure (s/first fragment/first fragment data/), but this would beg a definition of "how is a fragment composed?" i.e., what's "fragment data" and what's not).
