“‘As long as I do all the talking, things go all right,’”
Closing single quote was double quote in original

“when, where, and why.” 
Missing period in original

Chapter XXII “to go to bed agreeably”
              Corrected typo:  “agreebly”

Chapter XXIII “to participate in class discussions?”
              Corrected typo:  “discussions.”

In addition, in Chapter XVI a full line was missing.  The original reads: 

“And again, I command thee that thou shalt pray vocally as well
as well as in private.” (Doc. & Cov., Sec. 19:28.)

The corrected text is: 

“And again, I command thee that thou shalt pray vocally as well
as in thy heart; yea, before the world as well as in secret, in public
as well as in private.” (Doc. & Cov., Sec. 19:28.)
