I see the same effect on 2.5.0 and 2.5.1 running on Linux.
However, the following line reads the data correctly:
read.table('worms.txt', header=TRUE, quote="\"")
Thus the problem is likely because of single quotes in the Field.Name column,
perhaps a single quote character was added to the list of defaults since the
book was released.
