Part 12

On page 27, the footnote connected to the word “Wallach” was missing its number in the footnote, so a number was added for consistency.

On page 33, a missing “to” was added to “200° to 205°”.

In table VI, “50-mm. tube” was standardized to “50 mm. tube” for consistency with the text elsewhere.

In table VI, the formatting of the numbers in the “Fraction” column were changed from right-justification to left-justification to match the other tables.

In table VI, the formatting of the numbers in the “Rotation” column were changed to match the respective column of other tables.

On page 34, “Auwer’s” was changed to “Auwers’” since the name of the person is “Auwers”.
