Promotion-chasing Dalkeith completed a league double over Forfar at King’s Park last Saturday in a game of two halves.
Thistle hit the 40-point mark with seven crucial games remaining.
They raced into a deserved 3-1 half time lead but it was Forfar who dominated the second half.
However, the West Enders just could not score until a late penalty gave them some little consolation as Dalkeith held out for the narrow crucial victory.
During a positive start, Thistle opened the scoring in the fifth minute when David Liddle diverted a wayward Paul Tansey shot into the Forfar net.
