Bradford's History of 'Plimoth Plantation' / From the Original Manuscript. With a Report of the Proceedings Incident to the Return of the Manuscript to Massachusetts

m̄ and n̄ sometimes are used to represent a double letter.
16 li . represents 16 pounds in monetary terms. The original manuscript used a middle dot before and after the numbers, but this publisher used only a single period/stop after the number.
The 'li' appears to mean libra and in this book the 'l' is crossed with a middle bar or stroke. It was very difficult to represent in a Latin-1 text, so 'li' must suffice.
Most often y, such as y e , represents a thorn and the word is 'the'. Sometimes you will encounter the actual word 'the'.
This book is composed of many letters written by a number of authors and each writer uses their own spellings and abbreviations, which was common for the time in which they were written.
Spelling is inconsistent and is left unchanged from the original printing of this book.
