Elements Of Navigation Vol.1 - With Folding Star Charts Etc. For
Sale This excellent book is c.1765, perhaps a little later.
Since some of the examples refer to 1764I do believe it is
pre-1800 but more research required. Not in great condition -
REFER TO THE EXAMPLE IMAGES BELOW - but nevertheless packedwith
a copious amount of scientific and arithmetical information,
charts and tables, some torn.
