[seqfan] Need help with Escott sequence from 1903

Dear Sequence Fans, I have been going through photocopies of articles
from L'Intermédiaire
des Mathématiciens that I made 50 years ago.

There is one sequence that is a mystery, A350978, from
E.-B. Escott, Query 2521 <https://oeis.org/A350978/a350978.pdf>,
L'Intermédiaire des Mathématiciens, 10 (1903), 285.
You can see a scan of this page in the entry A350978. The original note
from Escott was written in English, but the journal translated it into
French, and the translation is hard to understand (my guess is the English
was also hard to understand).

We have 33 terms, computed by a famous American number theorist, with a
fuzzy definition. Could someone work backwards, and recover the correct

Or, go to some library that carries this journal (I saw it at Brown
University), and  find all the references to Query 2521. Each Query would
be mentioned several times in successive volumes.
The I.D.M. was like slow-motion email.

For other "new" sequences from this journal, work backwards from A350978
(and forwards - I still have another 50 pages of xeroxes to work through)

Best regards
