Henry, thank you for your fine essay on the time sight. I wonder if you ever came across Weems' The Secant Time Sight? It's really compact - 9 page sec/csc table, plus a two-page Rust azimuth diagram.

Thank you, Henry, for the effort you put into recording the history of the time sight. I have printed it out and tucked it into my 9th Edition (1894) of Captain Lecky's "Wrinkles in Practical Navigation", where , if the book survives, it may be found in another sixty years time by someone who knows nothing of the sextant or chronometer and who can scarcely credit that a GPS once had to be held in the hand.
I miss George Huxtable's contributions too. Are you still there, George?
Kind regards
