Interestingly there are 9 episodes on the release; whereas at wikipedia & other places only 8 are listed as comprising the 2 series
( plus the pilot : 'Lizzie Dripping & The Orphans' makes 10 programs were made in all).
The previously unlisted episode is the 1st episode of Series 2 & is called :
'Lizzie Dripping And A Wish'.
Maybe in the past this was confused with episode one of Series One which has a similar-ish title ie.
'Lizzie Dripping And The Witch'.
