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.
