On page 79, add comma after I remain in the letter. See page 95 of the 1869 novel.
On page 84, ferrule was an adjustment from the 1869 book, which only used one r in spelling the word (see page 101). Webster's dictionary spells ferrule with two rs.
On page 109, a period was added after "and the old man quite dotes on them". See page 130 of the 1869 novel.
On page 109, a period was added after "asked another voice". See page 131 of the 1869 novel.
On page 112, change colon to semicolon after "if you don't;"—see page 134 of the 1869 novel.
On page 113, transcribe ear-rings with the hyphen. See page 135 of the 1869 novel.
On Page 123, "One thing remember, my girls:" is written as it appears in the 1896 novel. A comma instead of a colon was used after my girls in the 1869 novel (see page 146). "One thing to remember," may work better today, or even "Remember one thing," but we left this as Ms. Alcott wrote it.
On Page 124, the P. C. is the Pickwick Club from a novel by Charles Dickens. Samuel Pickwick, Tracy Tupman, Augustus Snodgrass, and Nathaniel Winkle were introdued by Charles Dickens in the first chapter of The Pickwick Papers. Samuel Weller makes his first appearance in Chapter Ten of that novel.
On page 128, in the Pickwick Portfolio, there is no period after "it is nearly school time" in N. Winkle's letter. This period was also missing on page 151 of the 1869 novel. The missing period was intentional.
On page 135, the ambiguous punctuation after "Oh, dear, no!" is an exclamation point. See page 160 of the 1869 novel.
