Particular Case of the Hilbert-Waring Theorem -- Variant Form: $k = 7$: Historical Note

David Wells reports in his Curious and Interesting Numbers of $1986$ that:

All sufficiently large numbers are the sum of at most $137$ seventh powers.

At time of writing that may have been adequate, but since then the subject has moved on considerably.

The statement has been removed from later editions.
