The PSIs for the 1661 dates for 21 July, 22 July and 23 July had been incorrectly calculated in the conversion to Gregorian (see the previous note); these topic maps have been reloaded with corrections.

I checked the further entries with a rather natty multiple calendar converter here.

The corrected topics maps are:

• 21 July 1661
• 22 July 1661
• 23 July 1661
