The original printing was made before English spelling was standardized, and when printers, as a matter of course, expanded and contracted the spelling of the same words in different places, so as to achieve an even column of text. They set v for initial u and v, and u for u and v everywhere else. They used long ſ for non-final s. The glyph j occurs only after i, as in the final letter in a Roman numeral. Punctuation was relatively heavy and differed from current practice. When space needed to be saved, the printers sometimes used "ye" for "the", (replacing the Middle English thorn with the continental y), set ã for "an" or "am" (in the style of scribe's shorthand), and set & for "and". On the contrary, on a few occasions, they appear to have inserted these words when they thought a line needed to be padded. Later printings regularized these spellings; the punctuation has also been standardized, but still varies from current usage norms.
