The reprint is barely intelligible. As a professional navigator and student of horology and astronomy it is a very disappointing purchase.
The "tables" of pages 53 to 91 are not tables at all and
just a disconnected list of numbers; further the text has disjointed tabulations - refer page 1 of reprint eg The Agents (although not identified as such) at Aberdeen were Messrs A. Brown & Co etc - there is no correlation in the list of entries.
There are no diagrams nor tabulated picture of the Mariner's Calculator - refer page 29, 30 of the reprint, which (after considerable study) is a copy of page 104 of original, but it does not have any related illustration in www,general-books.net nor can any of the text be printed.
If Amazon or Google can provide any insight into these I would be most appreciative.
