I can confirm that this particular book is mentioned by name in the
"Notes for the Texture of Time" at the Berg archive, but I'm not
familiar with any specific treatments of it (and I do not discuss it in
any of my work).
" Has anyone previously noted Samuel Alexander's Space, time,
and deity: the Gifford Lectures at Glasgow: 1916-1918 in relation
to Ada? The text does in fact contain the "hours to a fly"
quote attributed to S. Alexander on pp. 542-3 of Ada. "
