[[end of page]]Transcription Notes:
By far one of the hardest to read and hardest to transcribe pages in the journal, due to crowding, bleed-through ink, etc. Researchers should double check every entry for accuracy. In some cases I have transcribed and aligned for mathematical clarity and/or continuity rather than transcribing text literally which would confuse context if transcribed purely by SI rules. Re "Bowditch": https://en.wikipedia.org/wiki/Bowditch%27s_American_Practical_Navigator. An encyclopedia of navigation. It serves as a valuable handbook on oceanography and meteorology, and contains useful tables and a maritime glossary.
